I’m getting the following error when using the mail-receiver app as of today. It was working fine before.
It’s trying to send the e-mail to Discourse via API. Is it possible it’s caused by DST Root CA X3 certificate expiration?
If yes, anyone has any idea about how to solve it? I tried to rebuild both app and mail-receiver, recreating Let’s Encrypt certificates, etc…
