Hi, Facebook not supporting SSL certificate in the webhook registration and I guess that in the application / canvas page creation.

There is a problem with your configuration, not letsencrypt : https://www.ssllabs.com/ssltest/analyze.html?d=montbot.com&latest the chain issue means you don’t provide the correct list of intermediates certificates

Because although the Ubuntu Xenia openssl package isn’t 1.0.2h, but “only” g, the 1.0.2g-1ubuntu4.1 does have th…

Please forget that “fix” immediately. Downloading source archives via FTP without verification and running code from it as root? What were you thinking?

[image] TCM: Downloading source archives via FTP without verification and running code from it as root? Good point, didn't even think about that.. You can download the source from a unsecured (e.g. FTP) source, but then you'd have to verify the download through a secured source, e.g. the SHA2…
