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.

I have the same issue, something is wrong enabling HTTP 3 and Plesk panel, it redirects to "localhost:8443" this happens to me when I click on extension Cloudflare to manage DNS.

Did you found a solution @andreios ?

FWIW Plesk Panel HTTP/3 was disabled by Plesk, by default in 18.0.61 mu3 > https://docs.plesk.com/release-notes/obsidian/change-log/#plesk-18061-mu3

However, it continues to be supported for all hosted sites. You can verify this via the CLI & Curl or even the Plesk Panel itself (Panel.ini Extention). We have zero issues with HTTP/3 in it's current Plesk config, works perfectly for us, but we don't use Cloudfare at all, so that might a factor in your case, maybe?

 

[ChrisMonder]

Yeah, I did that, disable HTTP/3 in Plesk Panel, and leave on the sites.

Thanks

No, no change. I still happen to me too if I try to enable it for panel. Seems they don't work on currently.

Thanks @andreios well we need to wait until Plesk have a solution for the Plesk Panel with HTTP/3 enabled on it.
