Hi @ashdam,

Thank you for your interest in ThingsBoard IoT Gateway. We was able to reproduce the issue and add a fix to master branch - https://github.com/thingsboard/thingsboard-gateway/commit/2030c90ae94c3103019ccb62e3b5199fb499e936

You can try to use a master branch or just add this commit via cherry-pick to release version. Or wait for new gateway release.
