Xwiki not replying after DEB update to 13.1

At Feb 24th I updated xwiki* on debian using apt from Version 13.0 to version 13.1.
After that I’ve to open the wiki and follow the instructions/assistent - at this day maybe I forgot this step (no access logged in apaches log which is reverse proxy for the xwiki).

This week I’ve to use the xwiki and did not get any reply in Browser (timig out).
I’m able to (re)start tomcat9 without errors in the logs. I changed verbosity (level) from “error” to “info” in logback.xml but I got no more useful information.

tomcat9 process is ruinning. I’m able to connct to tomcat via telnet. If I use w3m (text browser) on same machine its saying “IP contacted. Waiting for reply…”

Any hints how to fix my wiki? I’m not used to work with tomcat/java.

Following my catalina.out at starting tomcat9 using error verbosity:

Now the mentioned (warning) “context” in xwiki-tomcat9.xml file:

<Context path="/" docBase="/usr/lib/xwiki" containerSciFilter="org.apache.tomcat.websocket.server.WsSci|org.apache.jasper.servlet.JasperInitializer">
<Resources allowLinking="true" cachingAllowed="true" cacheMaxSize="32768"/>
<JarScanner scanClassPath="false">
    <JarScanFilter defaultTldScan="false"/>
  </JarScanner>
</Context>

That warning suggest you have path="/" in /etc/tomcat9/Catalina/localhost/xwiki.xml. This is not the default which is path="/xwiki" so I guess that’s a modification you made to make XWiki the default app.

Your guess is right. I edited my first post because somethin was “hidden”.
Changing path="/" into path="/xwiki" does not solve both warnings

[2021-03-04 15:04:19] [warning] The path attribute with value [/xwiki] in deployment descriptor [/etc/tomcat9/Catalina/localhost/xwiki.xml] has been ignored

I’m sure that I tried it already without succes but now my wikis are working again. Also in older backups I had path="/" - perhaps something in code changed?

There is no reason for the “/” to prevent XWiki from working especially since according to the log you pasted it was initialized fine. Seems to me the problem was that you were not accessing it with the URL you were using.

The problem is also with 13.2 und 13.3. So follow my new thread : https://forum.xwiki.org/t/after-starting-tomcat-webserver-is-not-responding-perhaps-solr-related/8693
