TLS Error: Unroutable control packet received

[MacUsers]

Dear all,

Running OpenVPN on 6100 (v22.05) and the connection is stuck at the Authorizing stage with this error on the server side:

Dec 4 22:23:27 	openvpn 	33226 	xx.xxx.xxx.137:5243 UDPv4 READ [755] from [AF_INET]xx.xxx.xxx.137:5243: P_CONTROL_V1 kid=0 [ ] pid=4195 DATA len=741
Dec 4 22:23:27 	openvpn 	33226 	xx.xxx.xxx.137:5243 TLS Error: Unroutable control packet received from [AF_INET]xx.xxx.xxx.137:5243 (si=3 op=P_CONTROL_V1) 

All of the google search on the error indicates a time sync issue between the server and client bit that doesn't seem to be the problem here.

the client side (Tunnelblick) simply just reports:

2022-12-04 22:35:37.698750 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
2022-12-04 22:35:37.698900 TLS Error: TLS handshake failed`

An identical setup runs on a Dell R220 works perfectly fine but not on 6100; Any idea what am I missing or need to look in.

Any kind of the help would be much appreciate.

You've said :

@macusers said in TLS Error: Unroutable control packet received:

Dec 4 22:23:27 ...... a time sync issue

Then you say :

the client side (Tunnelblick) simply just reports:
2022-12-04 22:35:37.698750 TLS Error: TLS

I say : compare the two time stamps. They are more then 12 minutes off.
Get your "time" fixed.

@gertjan Thanks fo rthe reply.
logs were not necessarily from the same session - I pasted the lines as reference to the error.

BTW, after increasing the log-level to 7, it reveals that the error was coming from the outdated CRL but the error reporting was very generic and confusing. It started working since this morning.
