Unable to follow GNU Social accounts
I haven't been able to follow GNU Social accounts from my Epicyon profile. GS users are unable to follow me from their end either. @administrator@gnusocial.net has shared the following information regarding this:
"I've done some tests trying to follow your account; it seems the ActivityPub profile can't be found. I don't know if it is a bug in Gnusocial or Epicyon; anyway, I'll report the bug. I'm afraid using the same protocol (ActivityPub in this case) is not enought to guarantee federation. For example, support for federation with Misskey was recently added in Gnusocial: https://notabug.org/diogo/gnu-social/pulls/279 "

Hope this helps in resolving the issue.
