SonicWALL VPN keeps going down

Hello all, I’ve ran into an issue at one of our remote sites. Every other day or so the VPN tunnel will go down and will stay down until the firewall is powered down and rebooted.

The connection is between a TZ300W and NSA 2400, granted the OS hasn’t been updated in a while but I have an identical set up that works fine.

I’ve tried going from AES to 3des, making sure on side is checking in, no matter what I do it’ll come up for the day then go back to what it’s doing.

I’ve had Comcast come out, I’ve change the appliance itself. I’ve tried contacting sonicWALL but never got through, our MSP hasn’t been much of a help either.

The logs are a mess, any help troubleshooting this would be appreciated.
