Hi For a while now I have struggled with a problem when trying to connect to a Ignition Edge gateway (8.3.2) from several computers, within the network and through VPN. Reading from a launch\_error-log it seems like it struggles with downloading a file called “security-8.3.2.jar” For “fun” I tried to put the url in a browser, where it also started downloading the file, but stops at around 15kb, eventually timing out. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/f/8f7fb4966a7b85daef94945454f3bebb9f1b8e99.png) Designer launcher is 1.3.2 on my computer and the problematic Ignition Edge is installed on ma Windows 10 IOT PC. I tried Ignition 8.1.50 earlier, and it worked ok. I tried to set "signature.verification.strength": "LOOSE" in the designer-launcher.json on my computer(s). There is no problem connecting to a similar Ignition Edge with same version on a Wago Edge PC. I’ve tried disabling the firewall Downloading "[http://xx.xxx.xxx.xx:8088/system/jar/m/security-8.3.2.jar](http://xx.xxx.xxx.xx:8088/system/jar/m/security-8.3.2.jar)" (timeout=60000)... Connect successful. Starting download of 18755 bytes Only read 15551 bytes in 60018ms! Download attempt #2 for file security-8.3.2.jar failed. Has anyone experienced this before? Looking for some tips on what to check. ---

You're going to need to look at AV/security software, firewalls, VPN configurations, etc... 10000% it's something doing packet/traffic inspection and a false positive is triggering on the contents of that JAR file. ---

Thank you, your response was spot on. Our connection is made through Cisco Anyconnect. I passed on your feedback, pushed a little. IT fixed it and referred to some documentation regarding this, so I guess they opened for download of [security-8.3.2.jar](http://xx.xxx.xxx.xx:8088/system/jar/m/security-8.3.2.jar) or something. > **[Snort - Rule Docs 1:45013](https://snort.org/rule_docs/1-45013)** > > Snort - Individual SID documentation for Snort rules > **[Snort - Rule Docs 1:45011](https://snort.org/rule_docs/1-45011)** > > Snort - Individual SID documentation for Snort rules
