Ubuntu 16.04 - Inactivity timeout (--ping-exit), exiting

Recommended Posts

edit: It works again. Have nothing changed. I think it was some hickups from hoster/airvpn or routing.

Hello,

I am still investigating this, maybe someone knows already what it could be.

OS: Ubuntu 16.04
No firewall configured. I have uninstalled fail2ban in case it blocks anything.

Problem:

My python script was working for months without any problems - all of the sudden it gets a ping timeout when I try to connect to any Airvpn server with netlock enabled (error log is attached)

I tested without '--netlock' and it is working immediately. I have not touched the server in any way. All of the sudden it just stopped working. The server generates a lot of traffic for the hoster, but I pay a bit more for unlimited bandwidth. At first I thought airvpn got rid of the server Ogma, but when I try without netlock it works.

my startup script (python):

os.chdir('/home/eddie-cli_2.16.3_linux_x64_portable/')
print('[+] Start eddie script.')
try:
    os.system("./eddie-cli --login=user_login --password=user_password --netlock --connect --server=Ogma >> airvpn.log &")
except Exception as Error:
    print('ERROR')
    print(Error)
print('[+] eddie script done.')
error log:
