Solved Lets Encrypt Certificate were not accepted/expired
I have the problem, that first Joplin don't accept the Certificate of LE and also my Banking Program Banking4W which save his data store on a nextcloud webdav directory, give me an error message, that the certificate is not valid.
I have no problem in Chrome or eath other, only in these both.
When I overrule TLS Certificate Error than all works well.
I regenerate all Certificates, but nothing change.
Nice evening, Axel
@roru2k20 Let's Encrypt recently changed the root certificate since the old one expired. The joplin client is being updated to accomodate this change per https://forum.cloudron.io/topic/5771/sync-error-certificate-has-expired . Not sure about the bank program, maybe you can check if it needs some update. Does the nextcloud client work?
@girish Oh sorry about that, I don't seem to have looked that closely for the topic so that I would have noticed it.
I already thought that it has to do with the Let's Encrypt exchange. Thanks for that.
My nextcloud has no error, only my banking app, but I would say it is the same reason and I must wait for an update.
