Ransomware protection blocks legit app

Recommended Posts

I'm running current MWB on Win 10 Pro. I also run Qlik Sense BI tool but today MWB has started to interfere with Qlik Sense.

Sense runs a local data connector on port 9051. If I enable Ransomware protection in MWB I get data connector not connecting errors in Sense. Disable it and all is well with Sense.

I tried adding the Sense data executables to the Allow list but no improvement. Any thoughts on how to allow localhost:9051 to be connected to by local apps without Ransomware protection getting in the way ?

Logs attached.

Add the executives to the allow apps that connect to the internet. Be sure to add the whole Qlik folder to the folder exclusions as well. Are there any other Qlik folders in program files or program files x86? Add them as well.

Also might want to report it as a false positive here. https://forums.malwarebytes.com/forum/191-ransomware/
