Connect button is greyed out when the layer url requires credential

[zen-coder-x]

I tested a layer URL that does not require credential and it worked fine.

It failed when I tried it with a Layer URL that requires credential.
It pops up the username and password to fill in.
The Layer Name had to be populated manually whereas the non-credential layer URL will populate the layer name automatically
I have tried different attempts but the connect button didn't seem to activate.

url was:
https://services.slip.wa.gov.au/arcgis/rest/services/WP_Public_Secure_Services/WP_Public_Secure_Services/MapServer/1

Hi @educit .
It seems that you found at least a missing catch in the code when there's a problem with authentication services.
Note that the plugin (and QGIS in general) supports only HTTP basic authentication and NTLM authentication.
Is there a public login to the URL of WA.gov.au you provided?
