Solved: The connection could not be loaded. Please try again later

Hi All,

I am in need of some urgent resolution. I am getting this error message every time I try to import my unmanaged solution. For context, I have a custom connector that is connected to an on premise data gateway connection. I have already searched other posts about this and none of the solutions worked for i.e importing Custom connector first or setting up the connection beforehand.

I have been trying to fix this since the past few weeks. Any help would be tremendous

Thanks!
