Hi everyone,

I’m trying to install xwiki on a debian10 virtualmachine.
I followed the instructions found on xwiki.org with the following package : xwiki-tomcat9-mariadb

After the installation, i try to install the standard flavor and I face the following errors :

xwiki error
xwiki error807×664 147 KB

Do you have any idea how to fix this?

Thanks in advance.

Maybe check SSL peer shut down incorrectly in Java - Stack Overflow

Some ideas:

  • Use -Djavax.net.debug=ssl,handshake to find out more or run nmap --script ssl-enum-ciphers -p 443 {HOSTNAME} to find out the versions of the security protocol is accepted by the host
  • Then use -Dhttps.protocols=... with the right protocol.

hi @vmassol , thanks for your answers.

I’m running the openjdk version “11.0.11”

By adding this line to /etc/default/tomcat9
JAVA_OPTS="-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2"

it seems to work
