Broken pipe on Ipsec connection

[Piougy]

Bonjour,


We have an installation of opnsense that was done in 2018. It is currently in version:

OPNsense 20.7.4-amd64
FreeBSD 12.1-RELEASE-p10-HBSD
OpenSSL 1.1.1h 22 Sep 2020

We want to connect our firewall via ipsec to a Microsoft Azure virtual network.

But we get the following message after a few minutes:

unable to sendback response [OK ] for [ipsec][connect][['con1']] {b9847368-4a32-4595-b5e6-fe3206240a73}, message was Traceback (most recent call last): File "/usr/local/opnsense/service/modules/processhandler.py", line 202, in run self.connection.sendall(('%s\n' % result).encode()) BrokenPipeError: [Errno 32] Broken pipe



The IPS service has been disabled. Thanks for your help
