Hello, @Elias Soares!
Thank you very much for your effort and input.
As our development team informed you in scope of the ticket you submitted, the issue should be already fixed by now.
In case it is not true for you, do not hesitate to contact us back in scope of the ticket.
Hello Alexander
The issue is not resolved in the version 17.8.11.
The workarround with the additonal nginx-directive doesn't work: it gives still the error message "The authorization token is not available ...."
But the solution from @Elias worked, but the the conf-files should not be modifed, and the changes go lost, after the files would be generated.
You also need to make sure Proxymode is unchecked under Domains > example.com > Apache & nginx Settings
Hi @Stefan Bättig,
I have just double-checked that thoroughly: you are right, it appears that common directory rewrite rules for nginx are conflicting in case proxy mode is enabled, so the bug is indeed actual.
I let our development team know about that, so hopefully it will be fixed soon!
Dear @Sebastian Thomas,
Thank you very much for the input, indeed: with disabled proxy mode it is working out of the box.
I try those workaround, but it's not working on my server.
The best way I find to do this is to remove the docker proxy rule from "/", renew certificate and create a new proxy rule.
Maybe plesk team have to set a rule somewhere on the proxy system to not proxy ".well-know"
Hello @Jérémy,
Thank you for sharing your user experience.
After the bug will be resolved, the article will be updated with the corresponding information.

There is a possibility that there may be some difference on your server.
I can suggest submitting a ticket to us or to our partner depending on where Plesk license was purchased from.

Hello @Stefan,

Please, try the solution from the article above.
In case this would not help, I would recommend submitting a support request to Plesk directly (if license key was bought directly from us) or to one of our partners (if license key was bought from them): https://support.plesk.com/hc/en-us/articles/213608509-How-to-submit-a-request-to-Plesk-support-
Hello @Alexandr and @Ivan
Are there any new news or when will the bug be fixed?
The workarround doesn't work:
I turned off proxy mode.
And of course I created the proxy rule, this is the real reason why the certificate can't be renewed.
Still get the message "The authorization token is not available at...".
We now have version: 17.8.11. #46
Thank you
Hello @Stefan,
The bug is fixed in upcoming extension version 2.8.0.
The ETA, for now, is the beginning of the 2nd quarter.
In case the issue will persist after the extension update, consider submitting a request for Plesk Support.
