Portal for ArcGIS not accessible on Web Adapter

[Kristofer]

Hello Everyone,

We are currently facing an issue with Portal for ArcGIS, Portal is not accessible with Web Adaptor.

Yesterday, we restarted the Portal for ArcGIS hosting VM by first stopping all Portal services and then rebooting the VM. However, after the restart VM, the Portal became inaccessible through the web server previously worked properly.

During troubleshooting, we observed the following: - In the Task Manager, only the “javaw” process is running, while the “java” process is not appearing, for Portal for ArcGIS these two services must be running.

Portal logs indicate major issues, including: - Indexing not functioning properly, Web server component not running and etc.

We referred to the solutions suggested by Esri Support and performed all the steps.

We have also repaired the Portal for ArcGIS installation but unfortunately, the issue persists.

We are using the below given environment

Portal for ArcGIS - 11.3

VM OS - Window Server 2019 (having sufficient RAM, CPU and Storage) 

A log file is attached here for your reference.

Thanks & Regards,

Kristofer

Hey @Kristofer 

We're currently using an identical setup, 11.3 with Server 2019, I'm curious if you've been able to verify that the IIS server running the Web Adaptor still has its binding? Kind of strange I know, but our server experienced something like this as well, and it turns out it lost its SSL certificate! 

This is about how it appeared, the Not selected was on the selection and it caused our Portal site to not boot up. In your case though it may be a little different, is the IIS server started as well? Also, since you mentioned you can't connect to the web adaptor, can you connect to the FQDN:7443 address?

Do you have an open case with Esri support? This is definitely a weird case so I would try to see if they're able to escalate it upwards in the management tree, it seems that it could be a corrupted configuration, I would definitely check the browser network and console inspector to see if anything gleams!

There are repetitive health check failures in the logs "Health Check failed, the portal is not ready. Connection to the indexer service failed."

Have you looked at https://support.esri.com/en-us/knowledge-base/how-to-rebuild-the-index-for-portal-for-arcgis-10-6-1-...

@Kristofer  There is an entry in the log which indicates you managed to login to the portal.

was it through internal url: https://domain.com:7443/arcgis ?

If so, are you able to access portaladmin and then look at index status and re-index it? You can check the machine health status too here. (it will be saying site not ready, until indexing is complete)

This will address index issue and possibly the health status too

Hi @Kristofer 

Are you able to log into the Portal Admin directory - https://<machine.domain>:7443/arcgis/portaladmin

Do you have certificate configured and default binding set to https

Did you tried to reconfigure your ArcGIS Web Adaptor?

Hi Team,

Thanks for the response!!

The issue is resolved now. We followed an alternative approach, summarised below:

Exported the Portal site using portaladmin → exportSite.

Stopped the Portal service and backed up the arcgisportal directory.

Cleared the arcgisportal folder (kept only pgsql_x.x.x and sql).

Renamed the config-store-connection.json file and restarted the Portal service.

Created a new Portal site using the existing directory paths.

Imported the previously exported site backup using portaladmin → importSite.

Verified that all items and federated servers were restored and the index status matched.

Thanks & Regards,

Kristofer
