Getting the error "Cannot contact reCAPTCHA"

[alphamale]

Anybody know what the issue is?

 

Tried this on both wifi and cellular. Ive just completed the design of the forum and nobody can register due to this?

That looks to be a front end issue, as in your user agent is unable to contact reCAPTCHA (or possibly their servers were down, though that strikes me as unlikely). Do you have any browser plugins installed that might be causing this? Ad blockers for instance?

I allowed these ips on my server's firewall and it fixed the issue:
