I’m not sure what I did, but I think I broke the NCP web interface a little. Everything else seems to be working fine – SSH, my WordPress install, NextCloud, encryption, NAS, etc. but when I try to do anything in the NCP web panel, I get “Invalid origin” errors (e.g., in nc-backup, letsencrypt, etc.). The System Info page looks good - everything appears Up and Running.
Unfortunately, I don’t know what I might have done and Google searches reveal nothing on the error. The last thing I did was play around with Certbot to get my domain up and running smoothly (which it is now).
Thanks for any help in the right direction!
