I've been trying to build a site to site vpn between my Sophos SG230 and my Sonicwall TZ350. I was able to get the vpn up and connected for about half a day, until the electricity went out for a few hours. Now I can't seem to get both firewalls to connect again. I have spoken with both Sophos and Sonicwall techs multiple times and they both assure me that it is set up correctly. I've called the ISP to make sure nothing is being blocked and there isn't. I've included screenshots of both firewalls as well as the error message I'm getting Both techs I talked told me it was an issue with the pre-shared key, but I have changed that several times and made sure that they are the same on both.
Basically, the error I keep running into is:
2022:06:17-14:34:43 74 pluto[22458]: packet from [remote site IP]:500: initial Main Mode message received on [HQ IP]:500 but no connection has been authorized with policy=PSK
