Issue HTTP/3 enable for panel redirects to localhost when changing E-Mail password

[andreios]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18.0.61 #3

I tried to change the password for an E-Mail (the admin E-Mail).
But after pressing 'OK' it redirected to this:

https://localhost:8443/smb/email-address/list/domainId/3

The password was changed anyway.
I checked if HTTP/3 is enabled:

plesk bin http3_pref --status
HTTP/3 is enabled for nginx

But I was sure I had enabled it for both -nginx and -panel. So I disabled HTTP/3 for panel. After disabling, I tested it again, no problems.
Probably the HTTP_HOST variable?

Can't comment on the e-mail aspect, as it's not something we've needed to do but, the initial question about the results of the "status" query has been raised before / answered before in amongst this post: Resolved - http/3 supported by plesk?

However, that ^^ was before Plesk encountered issues with MFA / Cloudfare etc (see several separate threads) which, has resulted in some 'temporary changes' by Plesk. Brief details and a link to the Plesk changes is here: Resolved - http/3 supported by plesk?

@andreios thank you for pointing that out. After the issues with HTTP/3 we're considering it an experimental feature. HTTP/3 support is disabled by default for all new installations now. Because it's experimental I would recommend not using it for the Panel and with caution for websites.
