Hello everyone, I have a problem with Cascaded WMS's on GeoServer 2.21. Some layers frequently report the error 'Connection reset' while some layers works fine.
This problem does not occur in a previous version 2.17.1 (using the same geoserver_data directory). I have tested the latest version 2.22.0 with the same result. My environment is: * Windows Server 2016 Standard * Java: Eclipse Adoptium JRE 11.0.15.10 hotspot * Tomcat 9.0.65 * GeoServer 2.21 Some Questions: * Is this a known problem? * Is there a way of increasing the logging in this area of GeoServer to see if the problem is in GeoServer or in the remote WMS server? * Any suggestions on how I can investigate this problem further?
