I am encountering an issue with my self-hosted V5 (v5.5.64-W105) White Label installation. The mobile and Windows desktop installations are working fine, and the client portals are accessible via browsers. However, the admin url cannot be accessed through any browser, including Edge, Chrome, and Firefox. All I get is a blank page.
I have tried several potential fixes and have researched the issue on the forum, but nothing helped. There are no error messages related to this issue in the log files, and even fresh installations are facing the same problem.
I would greatly appreciate your help in diagnosing this issue.
Thank you in advance for your support.
