Hi Christian,

now another error occured (see screan shot).


Reference from previous ticket

An error has occurred:
Toolset plugin cannot connect to
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 to remove this notice.

I checked the information in your site and the message indicates there is a problem with the registration here:
hidden link
"Installer could not fetch subscription data for toolset. Error message: Invalid site key for the current site."

Is it possible that the Toolset software suite was registered in a different site, then migrated to this staging environment? If so, then it may be necessary to unregister the Toolset software here: hidden link
Then re-register the software using the key provided for the staging URL in . I would try that first, then if that doesn't work delete the registration key for the staging URL in and generate a new key for the staging URL. Register with that new key at hidden link


Hi Christian,
as soon as I pushed my staging to live the issue was solved. Thanks for your help!
