Digi -> Digi IPSEC VPN Drops

0 votes
Hi

We have a S2S IPSEC tunnel betweend 2 digi WR21. The tunnel will establish and pass traffic and every now and again the tunnel drops and we get these errors in the logs.

A reboot of either side brings the tunnel back. Run a Diff on the config to make sure we're identical on both sides and it is.

Hi Chris and welcome to Digi Forum!

The retries exceeded error means that the remote peer is not responding within the timeout for all the possible retries. So the negotiation give up.

I would suggest you to check the network connection on the remote peer to see if any traffic is possible at all or if just the IKE traffic having issues.

If you still have issues the best would be to open a case sending an email to tech.support@digi.com. Please provide IMEI of both WR21 as well as a debug.txt (https://www.digi.com/support/knowledge-base/how-to-extract-the-debug-txt-file-from-a-digi-tran) taken from both when the issue occurs.
