cURL error 56: Connect tunnel failed, response 403

Hello,
we are trying to activate Wordpress X.

When its asking to type in the license code and hit enter a error appears after doing so: “Uh oh, we couldnt check if this license was valid. Details”.
Details shows: “cURL error 56 Connect tunnel failed, response 403”

Our firewall shouldnt block this. I didnt find this kind of error in the forum, so it would be nice if someone could help me fix this issue.

Best regards,
Harald

Hello Harald,

Thanks for writing to us.

It might be the issue of any plugin conflict, cache issue, or any browser extension that is stopping to validate the site. I would suggest you troubleshoot with our troubleshooting guide.

In case you haven’t seen our doc for license validation please have a look at it.

Please share your details in a secure note. Please provide the following details

  • WordPress Login URL
  • Admin-level username and password

You can find the Secure Note button at the bottom of your posts

Thanks
