Something went wrong! authentication errors

This error means your Redgate tools can’t verify your license because the authentication process failed. It usually happens when your login session has expired, there’s a network issue such as a firewall or proxy blocking access or you’re using an offline activation permit that has expired. 

Usually a refresh fixes it, but if the problem persists please try these steps:

1. Close SSMS
2. Navigate to your licensing folder
3. C:\Users\<your username>\AppData\Roaming\Red Gate\Licensing\Bundle-rg-tbe\<random UUID> or %APPDATA%\Red Gate\Licensing
    
   E.g.: C:\Users\My.Name\AppData\Roaming\Red Gate\Licensing\Bundle-rg-tbe\564n2a28vq3wyuphgmaa41ijfat28pvtmzc5zwcvb60iwgc853
4. Delete the Permits and Tokens folders:
    
   
5. Relaunch SSMS and set a new offline permit.
