Suddenly lost wan access - need help troubleshooting

[stuffu]

My opnsense has been rocks solid for a very long time, now suddenly I can’t access wan. No changes has been made for a long time and ping gives no response.

Tried restarting opnsense but nothing, running 24.1.9_4.

Wan seems to be working otherwise.

What can I do to troubleshoot?

edit: found an old router and replaced opnsense, working. I can't understand why it suddenly stopped and won't connect again.

When trying to resolve it today, I noticed there was a crash, probably causing the WAN connection to drop. Up and running again!
