Problem:
The following error message has appeared on the customer's website:
"Toolset plugin cannot connect to toolset.com
Toolset needs to connect to its server to check for new releases and security updates. Something in the network or security settings is preventing this. Please allow outgoing communication to toolset.com to remove this notice."
Solution:
Upon further debugging, after confirming that there was no block on the hosting side, we identified that there was a restriction in our servers regarding their IP, this usually happens due to the the amount of attempts or for using an old Types version.
Our system team removed the restriction and that got the error fixed.
