Xenforo Google recaptcha timeouts

@eva2000 i'm having the same issue, but i'm able to ping google from my server. i'm also getting 100's of recaptcha requests timing out from google. should i start a separate thread for this (i'm getting the same error on the sitemap as @KeVo)?

---

 

Sorry to keep bothering you @eva2000 but i've been having this error forever and don't know where to start diagnosing it. Any help would be much appreciated!

 

I only see the command for pinging Google, which seemed to work fine:

Code:

Here's one copy of each kind of error:

I was having one other error related to Google's recaptcha service, but I disabled it until I can get this worked out.

Obviously this is all related to Google somehow, so I don't know if perhaps the firewall blocked Google (the ports allow list seems good)?

I'm also running this by Linode's tech support, and we've only established that this *might* be related to IPv6? I can include those emails if it helps.

Here's where we are on that:

Code:

Hi,

These are your Linode's assigned IPv6 addresses:
Link-Local fe80::f03c:91ff:fedb:e6bd
Global 2600:3c01::f03c:91ff:fedb:e6bd/128

Here are the addresses it's currently configured for:
Link-Local fe80::4ed7:60bd:e63a:c5bb
Global 2600:3c01::ca80:8718:a8b2:524a

How are you configuring IPv6? Is there a reason why you're not using SLAAC? Please try configuring IPv6 statically[1] and then see if that helps at all.

Best regards,
JD
Linode Support

Thanks for the help!

 

Is it better to disable IPv6 or get this correctly configured to resolve these errors?

 

Is there a specific page in the online documentation for enabling/disabling IPv6?

 

Okay, well I followed the centos instructions for disabling IPv6 and the errors have stopped. In addition, one plugin that couldn't make its API calls to Google started working again. I also went back to using Google's captcha, which was previously causing 'could not connect' errors seems to be working fine as well. So, I'm going to stick with having IPv6 disabled since I don't currently have time to tinker with it.

Thanks to everyone for the advice and help, you're all life savers
