Hello,
I tried to upgrade a portal installation as described in this article (https://enterprise.arcgis.com/en/portal/latest/administer/windows/upgrade-portal-for-arcgis.htm). The Setup did complete successfully and I uploaded my licence file through the website. So far so good. But unfortunately I am not able to access the portal.
When trying to reach the portal home I get a blank screen. I did a bit of digging and I think this is the problem:
<Msg time="2020-12-02T15:58:02,331" type="SEVERE" code="218010" source="Portal Admin" process="2564" thread="1" methodName="" machine="PORTAL2018" user="" elapsed="" requestID="">The portal has been initialized and configured but is not accessible. The internal portal database does not appear to be running or accepting connections. Restart the portal machine or machines and if the problem persists, contact Esri technical support (U.S.) or your distributor (customers outside the U.S.).</Msg>
<Msg time="2020-12-02T15:59:11,403" type="SEVERE" code="218026" source="Portal" process="2564" thread="1" methodName="" machine="PORTAL2018" user="" elapsed="" requestID="">A valid connection couldnt be made to the index service. Verify the ports required by Portal for ArcGIS are open and restart the Portal for ArcGIS service. If the problem persists, contact Esri technical support (U.S.) or your distributor (customers outside the U.S.).</Msg>
I did try to find a solution, following some of the posts I found (https://community.esri.com/t5/arcgis-enterprise-portal/the-index-service-seems-to-be-unavaliable-please-check-the-index/td-p/41998) but I am also not able to login to the portaladmin (the portaladmin is accessible) where I get the Error, that I am not authorised to use this resource.
I tried several restarts, but no luck. Does anyone have an idea? Thanks in advance.
