I can't explain it, just had seen the error
and here it seems to have happened, too:

@olivierlambert
In that Browser I have even more blockers like AdNauseam + uBlock + NoScript, but the problem can be the same, just to remember that Browsers might have blocking utils in it if there is a problem for someone.

As I had now a chance to take a quick look, XO Light will be a great addition when it's ready

Currently I cannot test the Console, but the Dashboard looks nice and of course I would have some ideas what would be great to have there, but you might already have a list.
But I would say for troubleshooting to extract logs and use the bugtool might be handy to have available.

I could not get any VM button to do anything, it simply might not be implemented right now, like poweron etc.

But I have seen at least one possible problems that you might want to add to a FAQ:
If you have ublock adblocker installed it seems to cause problems if you don't whitelist:

@jameso said in XCP-ng 8.3 public alpha :

No offence to cocoon for doing great work with their release, but will v20.04.01 or variant be made available to support 8.3?

Just my 2 cents:
I think chances are a bit better now, because it looks like both teams (XCP-NG and Citrix) are working more closely together now.
In the past I would have said that development goes much more in different directions and so new things would usually not be added to the client as nobody is really working on it.

But now it could happen maybe if release is near or ready. I would not expect it for alphas and betas, but mostly depends on if @borzel will find the time then.

@stormi I will add some details here:

https://github.com/cocoon/xenadmin/blob/ddc54106203a6030d6e45955937ea769c7441e67/XenAdmin/MainWindow.cs#L946

This was my "hardcoded" value, that is not intended to be used here.

Instead the official way is to extend some Enums with supported API Versions.
If the Version of the host (for 8.3 it is 2.20) is not found in the enums, it get's set to 99 = Unknown.

The current enum contain only up to 2.16 (API_2_16) so API_2_20 is not found --> set to 99:
https://github.com/xcp-ng/xenadmin/blob/development/XenModel/XenAPI/ApiVersion.cs#L38

Problem is here where it compares the min version to the current and if it is higher (and it is with 99) it refuses to connect.

https://github.com/xcp-ng/xenadmin/blob/development/XenAdmin/MainWindow.cs#L928

As I hardcoded it to a lower value (20) it is now lower and allows to connect.

And btw: my build was based on a slightly newer commit from Citrix than the one at xcp-ng repo.

@stormi That is my special build where I "fixed" the min version problem that now is in the other "official" client ^^

was here back when the previous relase had no working client for some time

So still have the problem today on the upgraded VM that no https is available.

I installed a new VM now and there it works and I found these differences, looks like the /etc/xensource/xapi-ssl.pem file is too old.

@olivierlambert you're right, there was an error message, no redirect! Something like access denied or similar ...
