I use Nextcloudpi in the latest version. I cannot renew my Let’s encrypt certificate, it fails with the following error

If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided. Done. Press any key...
Actual domain is name replaced in the error message.
The nextcloud instance is still available from the internet and port-forwarding is configured and unchanged from previous successful renewals. It may be possible that i messed up the apache2 virtual hosts configuration. What’s the best way to check?
Any help is appreciated
