Forum Registration Not Working Correctly - Help Needed Please

[Ryan Sitzmann]

I recently converted over my forum (forum.idpguru.com)  to a custom subdomain and had nabble enable HTTPS. The forum itself is working as expected and is now encrypted; however, any time someone registers for a new account they get the following error message.

"Oops... An error has occurred
Please contact Nabble Support and explain what you did to cause this error. Your feedback is very important to us.

Can you please help me rectify this issue?

Happy to provide any additional information that may be needed to troubleshoot/correct.

Thanks,
Ryan

[Israel <Nabble>]

We will check this for you.
You will get a reply in the next few days.

[Ryan Sitzmann]

Hi there,

Just checking in to see if there are any updates here? Let me know if you need any other information.

Thanks,
Ryan

[Israel <Nabble>]

We have checked and your IP address is not ours. Do you have some kind of proxy?

[Ryan Sitzmann]

Yes, I just noticed it was proxied (I run my site through Cloudflare CDN). I just made it DNS only and it seemed to fix the issue. Thanks!
