Hello Sorato Marques,
Just to confirm if you try to access ArcGIS Server manager over 'HTTPS' using your web adaptor does the page fail to load?
Example URL: https://hostname.domain.com/webadaptorname/manager
If you sign into the ArcGIS Server admin endpoint what URL is listed for the web adaptor?
- ArcGIS Server Administrator Directory > Home > system > webadaptor > webadaptorID > URL
- Example URL: https://hostname.domain.com/server/admin/system/webadaptors/3fe5fd44-dbd3-4c0a-9662-2bc32aaecce8
If you open the web adaptor configuration page click on server and click next. What URL is listed to access the service directory?
- "Use the following URL to access the Services Directory:"
Finally this problem may be caused by the invalid certificate. I would recommend configuring a valid certificate with ArcGIS Web Adaptor and ArcGIS Server.
Hope these suggestions are helpful.
Thanks,
Thomas.
