Java download application timeout

[jpcei]

When accessiing to a government site, it's asked to download a Java application, which never gets to be downloades due to timeout exception.

in the details description of "Unable to launch application" in Java, i get this error:
com.sun.deploy.net.faileddownloadexception: unabel to load ressource http://download.gep.mtss.gov.pt/sguri/apps/lib/avalon-framework-4.2.0.jar

i tested this java application outside the OPNSense firewall and it works well.

Any ideas of what can be stucking this ?

Can you check if the same happens when you use a browser?

[jpcei]

this happen in any browser on PC's in the LAN.

So the reason can be the Proxy in case ICAP is used and streaming is enabled (an AV marks it as malware), or an IPS rule.

sorry for the delay...

I can't get which rule is making this kind of struggeling

i already stopped suricata service, which i suppose in that way should not apply any rule, but same result... it hangs in download.

Today i tested again, the same way, this Java application, and it works correctly... no changes have been made in OPNSense, so i must suppose, something has change from the server side in mtss.gov.pt, somekind of correction in the java applet, or a new certificate applied.

By now is solved for me, but for those who reads this post, and are having same kind of problem, i can´t point the solution from OPNSense side.
