GIVTCP not connecting to invertor

Hiya, wonder if anybody is having issues with givtcp2

i have set up my HA and installed the broker with local user and then GIVTCP

However it juts always fails to connect. i can access my GivEnergy locally so i know its there haha and it also exports to the invertor app every 10 secs so i know the data is there. here is my log. if anybody can shed any lite that would be great. i have tried it as a AIO and also using the old firmware toggle

Not providing an answer here, only saying I have exactly the same issue and it occured about the same time as your post.
I also tried toggling the ‘old firmware’ and AIO options in different combinations but that didn’t work either.

I wondered if the IP had changed so it was looking in the wrong direction but that doesn’t seem to have changed.

I hope someone more savvy than us has found a solution!

Hi All.
I’m also having exactly the same issue although with a Giv Gateway and All-In-One. Any updates would be greatly appreciated.
Cheers.
