i did the following but non of them worked:
1- Copied sharedWebConfig.config file from C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy directory and pasted "replaced it because it was already exsits" it on sharedWebConfig.config file in C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess directory + IISreset
2- I checked IIS frontend\ backend binding and it were pointing to third party certificate " as other exchange servers".
3- webconfig was exsits on OWA\ auth\ client axxess folders "not missing".
4- I checked fronend OWA\ ECP physical path and they are correct.
I noticed that haredWebConfig.config is exists on one exchange server only "the one having the issue" and not exists on the other exchange servers and i search inside it for exchange server name and it was pointing to another server.
What else can be done to solve this issue.
Thank you

The issue has been solved. A web developer creates "copy" web.cofig file on wrong directory which caused the issue. i just delete it and OWA/ECP worked fine.
Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\owa\auth\web.config
Hi @HamoudaAlbakri-3924 ,
Did you change any settings before this error occurred?
Is the problematic Exchange server in a DAG environment?
Please following the steps and see if the issue is resolved:
1.For Exchange CU11, please make sure that the Microsoft .NET Framework version is 4.7.1 or 4.7.2.
For more information:Supported .NET Framework versions for Exchange 2016
2.Please run the following command line to check the settings of OWA and ECP, check whether there is a difference between the configuration of the normal Exchange server and the configuration of the Exchange server that has problems.
Get-OWAVirtualDirectory | fl
Get-ECPVirtualDirectory | fl
3.Please run UpdateCas.ps1 and UpdateConfigFiles.ps1 from the exchange bin directory C:\Program Files\Microsoft\Exchange Server\V15\Bin. And please run the IISRESET in CMD start as administrator to restart IIS.
4.Please check if there exist MSExchangeECPAppPool and MSExchangeOWAAppPool in the Application Pools in IIS. If they exists, please make sure the .NET CLR Version is v4.0 and right click, then select “Recycle”.
5.You could run the following command to remove and recreate the virtual directory.
Remove-OWAVirtualDirectory
New-OWAVirtualDirectory
Remove-ECPVirtualDirectory
New-ECPVirtualDirectory

Hi
I would advise upgrading to CU17 and applying the security update as well. CU11 is behind and you missing out on major updates.
We got Microsoft support "issue with OWA - too many redirect" and got solved by running a script. After that i test all exchange servers OWA\ ECP per server and everything was working fine.
