The bimcloud server is not accessible, due to insecure http connection. This only occurs on MacOS (Venture 13.6) when connecting through Archicad, while on Windows and access through the browser works fine.
To me this looks like a MacOS setting issue (but I am not sure) and I have no idea how to solve it.
I had a similar issue where strangely I couldn’t access the BIMcloud when I was on the internal network but could when I connected from home through VPN. I had to open the BIMcloud port on our router and then it worked. Almost like the connection to the Server goes out of the building and back in through the router instead of direct through the internal network. The domain nor the IP address worked.
