RB750Gr3 - no traffic in IPsec tunnels

Patient: RB750Gr3, ROS 6.48.1
A few hours ago, traffic inside the IPsec tunnels stopped. There are two tunnels configured - one acts as an initiator, the other as a responder to two different routers that work properly. I am able to reach the router using its external address, but nothing works on local (input as well as forward to the internal network). Configuration unchanged, no updates before. Updated to 6.48.3 when trying to solve the issue (firmware and OS), no changes. Hardware failure? Have any of you met with such behavior?

I want repaint my house with same color of my friend house, how much paint I need and what color should I buy it?
