@arslane and @sabedevops this error seems consistent with the recent csdk (which the python sdk uses) switch to openssl. I published new quickstart containers last night and published a discourse post yesterday but it didn’t occur to me for some reason to expand it to other sdks in the title. I fixed that just now.
Could you have used a quickstart to deploy the network? Could you check the controller field as listed in the post here PSA - quickstart change for latest tunnelers and c/python/swift/node sdk ?
