It works fine with the postsql db installed on the same host but got a "500 internal Server Error" when connect to an external db. The db is not a issue because if I remove the settings, it works for both local and external db. I didn't find any useful logs. Can someone guide me how to troubleshot this issue? <div><br><div><br><div class="rte-style-maintainer" data-color="global-default"bbg-color="default" data-bb-font-size="medium" bbg-font-size="medium" style="font-size: small; font-family: "Courier New", Courier, "BB.FixedWidth";"style="font-size: small; font-family: "Courier New", Courier, "BB.FixedWidth"; color: rgb(0, 0, 0);"><div class="bbg-rte-fold-content" data-header="From: Bin Li (BLOOMBERG/ 120 PARK) At: 03/10/22 10:42:23 UTC-5:00"data-digest="From: Bin Li (BLOOMBERG/ 120 PARK) At: 03/10/22 10:42:23 UTC-5:00"style=""><div class="bbg-rte-fold-summary">From: Bin Li (BLOOMBERG/ 120 PARK) At: 03/10/22 10:42:23 UTC-5:00</div>To: <a spellcheck="false" bbg-destination="mailto:pulp-list@redhat.com" href="mailto:pulp-list@redhat.com"> pulp-list@redhat.com</a><br>Subject: webserver authentication</div><br><div class="rte-style-maintainer rte-pre-wrap" data-color="global-default" bbg-color="default" data-bb-font-size="medium"bbg-font-size="medium" style="white-space: pre-wrap; font-size: small; font-family: "Courier New", Courier, "BB.FixedWidth";"style="white-space: pre-wrap; font-size: small; font-family: "Courier New", Courier, "BB.FixedWidth"; color: rgb(0, 0, 0);"><div>We are currently use the below setting for webserver authentication.
