      Can you check since which commit you have the issue? (eg just before the commit that @ronivay pointed to you)

        Try to get on commit b9ff3db9b0e023aef36961d0127a266ae2b621a6 (just before c99120bd24b3b73128a0944bb54d4f1dd6ed61e8), rebuild and try again πŸ™‚

          after googling some git commands; im not very versed in git at all, so not sure how to get that. πŸ˜•
          this is the one that last worked for me, and the one im currently using. I save the last 3 in @ronivay script.
          v5.16.0-8953-g04913cabb

          this is the one that I pulled and it seems to break:
          v5.16.0-9058-gf6e1b9571

          I see another comment on the issue tracker from @ronivay. I'll try to get to his suggestion a little later.
          and just to link these two together for someone in the way future:

            @olivierlambert , I received exact instructions from @ronivay on how to do that. Using commit b9ff3db9b in my new temporary install of XO, everything works fine.
            Moving to c99120b seems to break the console on anything other than XCP 8.2.
            And I've mentioned before I think: all of our hardware does support XCP 8.2, but almost none of the RAID card monitor software works there. 80% of them are using 3Ware/ LSI 9750's. I can't recall the exact problem, but the executable for the web-admin doesn't run.

              1. We'll restore backward compatibility and fix that ( @florent will fix that commit). Thanks for reporting it πŸ™‚
              2. Your previous XCP-ng installs aren't patched anymore, so you are at risk. You should really migrate to it, regardless the rest (and maybe seek for a solution for your RAID monitoring, but installing stuff in dom0 is not recommended in general). At least this advice worth for production use, not home lab.

                    hrm, well, I bumped my temp install of XO back to the master branch, and consoles broke. -Appears- to only broke with XCP 7.6. 7.1, sites worked.

                      I can also reproduce this with XCP-ng 7.6. I’ll try to do some additional tests. Let me know if there’s anything i can assist with.

                        Okay we tested with XS 7.1 and XCP-ng 7.5, without any luck πŸ˜•

                        Can you describe a bit more your test protocol?

                          @ronivay I did a lot of tests yesterday (master/latest/old and new commit) , with a wide range of xcp and didn't reproduce it

                          Do you use any http proxy between XO an XCP ? Do you use some kind of network filtering ? do you use xo in HTTP or HTTPS mode ?

                            Interestingly console for some old VM's with old OS are working, like centos 6, debian 8 but anything above those (centos7, debian 10, debian 11) aren't. I'm getting same errors in browser as listed by @bberndt earlier. This can be found from host xensource.log

                            So far i've tested with XO built with XenOrchestraInstallerUpdater (obviously ;)) and also built one manually, same symptoms. I've tried XO with and without reverse proxy, with http, with https, with one in same private network as XCP-ng host, with one connecting to it over VPN. No special firewalling or filtering in between and no HTTP proxy.

                            But as the error from host says, it sounds like it’s simply missing support for this type of console connection.

                            E: and just for the record. wsproxy package is installed:

                            # rpm -q wsproxy
                            wsproxy-1.6.0-4.el7.centos.x86_64

                              @ronivay Do you mean it works for PV guests but not HVM ones?

                              edit: that might be the reason why we can't reproduce since we probably test on PV guest πŸ€”

                                Yeah good point, all those old ones are indeed PV guests and all the rest are HVM.

                                  @ronivay that's a great information. I can reproduce the comportment with xenserver 7.1 CU 2
                                  Thank you

                                    @ronivay @bberndt Could you try this branch fix_console_proxy_xcp_7x containing a quick fix (fallback for older hosts to the old method)?

                                    from this PR: https://github.com/vatesfr/xen-orchestra/pull/6191

                                    fbeauchamp opened this pull request in vatesfr/xen-orchestra

                                      Thanks. This seems to fix it for me at least. XO logs UNEXPECTED RESPONSE and FALLBACK for those HVM VM's and console opens up fine.

                                        @ronivay yeah

                                        I'm making a little code cleanup before merging in master (removing console , adding changelog)
                                        We'll probably make another patch release with this fix.

                                        I'm glad you saw it and give us such a precise feedback.

                                          When I tested yesterday, this was on HVM guests.

                                            You need both HVM guest AND XS < 7.2
