          @olivierlambert Nope, what I understand is that it appeared somewhere between 36edfdc64 and 9686af970.

          Also, none of these commits are on the master branch.

              @olivierlambert I was thinking he's talking about a commit number from the third party installer ronivay/XenOrchestraInstallerUpdater, but i couldn't find the commit either.

              @dsiminiuk Can you tell us the commit number displayed in the page "about" ?

                    @dsiminiuk Unfortunately that does not help me a lot, I don't see what change could have trigger this behaviour.

                    Is there anything in xo-server's output?

                    Also, doing the bisect search to pinpoint the precise commit (as explained here) would help a lot.

                      I am having this same problem.
                      In my case it was because I used a not so clean debian system.
                      I solved it as follows:
                      I installed debia with minimal configuration, In Software selection, select only "SSH server" and "standard system utilities"
                      already as root in debian I gave an apt update

                      Config static IP:
                      nano /etc/network/interfaces

                      	# The loopback network interface
                      	auto lo
                      	iface lo inet loopback
                      
                      	# The primary network interface
                      	auto eth0
                      	iface eth0 inet static
                      		address 192.168.1.101
                      		netmask 255.255.255.0
                      		gateway 192.168.1.1
                      

                      #Address, netmask and gateway change according to your network

                      #Config SSH:
                      nano /etc/ssh/sshd_config

                      	Modify the line:
                      		#PermitRootLogin prohibit-password
                      	To:
                      		PermitRootLogin yes
                      	Restart ssh:
                      		systemctl restart sshd
                      	It is now possible to connect to Debian via SSH
                      

                      #Installing XCP-ng Tools

                      mount /dev/cdrom /mnt
                      cd /mnt
                      apt install ./xe-guest-utilities_7.20.2-1_amd64.deb
                      

                      #Install Xen Orchestra with script:
                      apt instal git
                      git clone https://github.com/ronivay/XenOrchestraInstallerUpdater.git
                      cd XenOrchestraInstallerUpdater/
                      cp sample.xo-install.cfg xo-install.cfg

                      Edit xo-install.cfg depending on your needs.
                      
                      ./xo-install.sh
                      

                      #First Configs:
                      When installation is complete, browse the WebUI.
                      User: admin@admin.net
                      password: admin

                      Go to Settings > Users
                      Create a new User with Admin powers
                      Log out of the WebUI and log in with the User created
                      Go to Settings > Users
                      Select the User admin@admin.net and click Delete User
                      
                      Go to Settings > Servers
                      Add your XCP-ng server and click Connect
                      In Status if a red exclamation appears, click on it and accept the self-signed certificate

                        Hi,

                        I'd like to remember that we can't support 3rd party scripted installs, just following our doc isn't that much complicated: https://xen-orchestra.com/docs/installation.html#from-the-sources

                          @Finallf gave me a clue, about accounts.

                          I switched back to master f28721b84.

                          When I login with admin@admin.net I can see the one Online host, but not the Offline host. Removing the filter "power_state:running" did not reveal it.
                          I powered up the 2nd host and now I can see both online.
                          Logged out.

                          Logged in with my personal account which is also an Admin.
                          Could not see any Hosts listed.
                          In account settings I cleared the filter I had previously saved by the name "None" (so that the pesky power_state:running didn't have to be cleared every time), and now I can see both hosts online.

                          When I power off host#2, I can not see it listed on the Hosts page using either account.

                          Not seeing ANY hosts appears to have been caused by the filter being corrupted or no longer valid for whatever reason on the personal Admin account.

                          However, I should now be able to see the online AND offline host, and it it is not listed using either Admin account.

                          Better, but still something wrong.

                              Something else Hosts related...
                              When I click on the Pools list, I see my pool. I click on it and it shows me the 3 icons. The 2x server icon, 3x Storage SRs and 10x VMs.
                              4f317974-e440-4f73-b193-10c4a2b68bd7-image.png
                              if I click on the Storage Icon it takes me to the storage list http://xo/#/home?p=1&s=&t=SR
                              if I click on the VM icon it takes me to the VM list http://xo/#/home?s=$pool:ac9585b6-39ac-.....c082b
                              But if I click on the Server icon I expect it to take me to the hosts list (even if it is only the one I see) and the the page freezes and never comes back.
                              Refreshing the page gives me the "circling the drain" logo forever.
                              However, I can click logout on the left menu and log back in and it's fine.

                              I will try a rebuild from scratch.

                                @Finallf I built a new minimalist Ubuntu 22 server and followed the same path and it does EXACTLY the same thing.

                                  I tried to build from sources at the link you provided and there are instructions missing or things not obvious to me.
                                  From /root I did git clone.
                                  cd packages/xo-server
                                  "Note: If you're installing xo-server as a global service, you may want to copy the file to /etc/xo-server/config.toml instead."
                                  OK, I want to d othat so I cp sample.config.toml /etc/xo-server/ <- this directory does not exist
                                  So I crated it and copied it there, but that is the only file there now.
                                  Then I went back to /root/xen-orchestra/packages/xo-server
                                  yarn start

                                  yarn run v1.22.19

                                    I've managed to get the build from sources to work and it does EXACTLY the same thing.
                                    That excludes the XenServerInstallerUpdater as being the problem.

                                      @dsiminiuk If you cannot pinpoint the problematic commit, you can deploy an official XOA, then open a support tunnel and we'll be able to check it out directly.

                                        @julien-f I tried that but got "An error occurred", but I saw at my host's address (after accepting the SSL certificate alert a directed) that it could be deployed from right there so I tried that and got another error.

                                        841ac303-3e0e-42ad-9441-2c624fadd81b-image.png

                                        If you can give me the master commits from newest to oldest over the last two weeks I can try those one at a time. I have no idea how to find them.

                                            @olivierlambert I will try that on the new VM I built last night since it is built from sources per your doco. I could not use that for the xo deployed by ronivay's script.

                                            Additional observation: The behavior I see when there is one host online and another offline (web page freezes when clicking the Hosts icon from the Pool view) does NOT happen when both hosts are online (perhaps that there are no hosts offline). This is a clue as to the source of the issue.

                                            Am I really the only user seeing this?
