Cant access login page of AE (This page can’t be displayed)

[Boris Znahor]

On AE 12.3 server I tried to upgrade apache tomcat 9.0.19 on latest version with this instructions (Upgrading AWI Tomcat Version)
After upgrade and restart could not open login page of automic. I have restored apache to 9.0.19 but still no luck, cant access login page.

Error I get:
This page can’t be displayed
Make sure the web address http://awat001:8080 is correct.

I try to run start.bat and startup.bat from bin folder on tomcat but nothing changed. Any idea what is wrong here?

Hello Boris, if you upgrade from 9.0.x to 9.0.x it should work as before, check the Tomcat logs (catalina.X and look for errors).
On the other hand, upgrade from Tomcat 9.x to 10.x may not work as Tomcat 10 is not supported in AWI as you can see here

I ran into Tomcat errors when I upgraded to 12.3, too. You definitely have to check the catalina log to find the error detail, not any of the Automic logs. 

Here's a link to the KA from my problem. I don't know that it will help you with your problem, but FYI:

I checked log and found problem. It was java which I update before apache tomcat. Since is new version of java JRE_HOME path should also changed in apache. Now I have new error. I have login page but when I try to login this error shows:
com.uc4.ecc.backends.exceptions.AutomationEngineAPIException: Error during XRequest com.uc4.communication.requests.GetRestEndpoints
Solution to this should be https://knowledge.broadcom.com/external/article/200060/unable-to-access-awi-after-upgrade.html but is unclear for me where should I apply this?

Have you checked the uc4config.xml of your AWI to see if it has the correct information to connect to your AWA?
When you upgrade the AWI, you need to restore the files in the config folder, else you will start AWI with a template configuration file where the target CPs are not inside the file.
If you did so, and started the CP/JCP processes, it should work, else send us the uc4config.xml and the output of the query
select oh_name,host.* from oh,host where oh_idnr=host_oh_idnr and host_hostattrtype in ('W','C');

Thanks
