It is a very odd behavior, and confused me recent days. The application will lost response sometimes in a random chance, the client cannot get any response from the server.
First, the Tenancy specified access lost response from the server, then if clean the client cookie, it could access to the Host dashboard, but cannot impersonation to any Tenant, if try to impersonation a Tenant, then it will blocked on the redirect screen.
After several tries, the Host dashboard also will lost response from the server, by this time, all site lost response from the server.
The odd thing is all of these behaviors without exception logs to record, the server level or the application level both are looks work good, and the w3p.exe, application dotnet.exe both are working fine.
During the no response time, the application logs recorded request are received by the application, but cannot return any result to client. It will stop after redirect the route to login action of the account controller.
Every time encountered this behavior only restart the application pool could let the application run normally, no other approach can fix it.
Anybody have this issue too?
It is running under Zero v5.5.0, host on IIS 10 on Windows Server 2012 with SQL Server 2017 as the DB server.
