1. Grey screen at login - Firewall settings
If you get a blank grey screen when logging in and the following link appears in your browser, there is a firewall problem:
https ://filing.cbso.nbb.be/?error=server_error&error_description=AADB2C90047%3a+ The+resource+%27https%3a%2f%2fcbsostorageappp.blob.core.windows.net%2fb2c%2fux%2fnl %2funified.cshtml%27+contains+script+errors+preventing+it+from+being+loaded
This problem is due to the firewall settings on your PC and can be solved by allowing the following urls into your firewall or that of your company:
login.microsoftonline.com
cbsostorageappp.blob.core.windows.net
b2clogin.com
