Hello
Client don't want to start, explanation is :

Caused by: net.sourceforge.jnlp.LaunchException: Fatal: Application Error: Cannot grant permissions to unsigned jars. Application requested security permissions, but jars are not signed.

Seems it is this one :
Jar found at /home/bruce/.cache/icedtea-web/cache/6/https/fumbbl.com/FFBClient/live/org.osgi.core-4.3.0.jarhas been verified as UNSIGNED

I run FUMBBL on a Chromebook and recently I have found I can rarely get onto the client using it.

It sounds like I had a similar error message to you.

As I couldn't resolve the problem, I've gone back to using my old laptop. Sad

This came up on discord yesterday.

seems the latest update has set to default that the jars need to be signed. first answer here will see you right Very Happy https://unix.stackexchange.com/questions/143805/running-unsigned-javaws-code

Yep, I commented out the lines containing
Code:
disabledAlgorithms

and that fixed it.

I had to follow the second option on Ubuntu. Posting here in case it helps others as took me ages to find the right file.

Security Fix #1
~/.config/icedtea-web/deployment.properties
change
deployment.security.level=ASK_UNSIGNED
to
deployment.security.level=ALLOW_UNSIGNED

Security Fix #2
/etc/java-11-openjdk/security/Java.security
Had to chmod the file to edit and then remove MD5 from
jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024
