I tried to start the Blynk-Server on my Server but only get this:
root@localhost:~# java -jar server-0.41.1.jar -dataFolder /home/blynk &
root@localhost:~# WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.
Error starting Blynk server. Stopping.
My java version is:
root@localhost:~# java -version
java version “11.0.1” 2018-10-16 LTS
Java™ SE Runtime Environment 18.9 (build 11.0.1+13-LTS)

root@localhost:~# cat /etc/os-release
PRETTY_NAME=“Debian GNU/Linux 9 (stretch)”
I also tried to use several releases but got the same error everytime:
Does anyone has any suggestions?
Hello. Do you see some errors in the
blynk.log file? Most probably you have busy ports.
There is no blynk.log file.
root@localhost:/home/blynk# ls -la
drwxr-xr-x 5 root root 4096 Jan 7 22:41 .
drwxr-xr-x 3 root root 4096 Jan 7 22:40 …
drwxr-xr-x 2 root root 4096 Jan 7 22:41 backup
drwxr-xr-x 2 root root 4096 Jan 7 22:41 clone
drwxr-xr-x 2 root root 4096 Jan 7 22:41 deleted
I also looked in /var/log/, but there is also no blynk.log
Hi, I have same problem and solved it, by using change the folder name from blynk to Blynk. I hope benefit for you.
Wow, hard to believe, but that actually solved the problem.
Thank you so much!
