I am a happy blynk user since about two years now. Lately I came up with a new project and experienced some issues so I thought to update the Blynk server from 0.30 to the latest version 0.41. Then the devices could not connect to the server anymore (app could!) and problems began…
Long story short, I found out that the last working server version is 32.2. According to the changelog, the old hardware server on port 8442 was removed in version 0.33 so this seems to be the root of my problem.
I am running blynk server (java 8 version) on a RPi 3 and can see that the Ports 8441-8443 are nether initialized during server startup log nor are they opened on raspbian.
I thought of a bug first but I’m sure I’m not the first person experiencing this problem after so many releases in the meantime.
So, here’s my startup log:
23:38:38.901 INFO - Using data dir ‘/home/username/Blynk’
23:38:41.269 INFO - Region : local. Host : sub.domain.tld .

I would be grateful if someone could help me solvong this problem, especially in respect of the removal of old Hardwareserver and why the new one seems not to start…
