Cannot get LNC to work

[benthecarman]

I cannot get LNC to connect with Zeus or the Lightning Terminal website. Every time I try pairing I get this error:

Refreshing the page or creating a new pairing phrase yields the same results

We'll be adding more details to that error shortly. In the past, the cause of the issue has been due to your admin.macaroon being created by an older version of lnd which doesn't have the proper permissions for LNC to function properly. This fix is to delete the macaroon then restart lnd and litd.

Let us know if that works @benthecarman, if not, we'll have to dive in deeper to debug.

That worked, thanks!

After months and months of running into this error message, trying at various times with different versions of litd, messing with networking settings, and scouring logs for clues, I was able to get LNC working finally by deleting and regenerating my admin.macaroon (I also had to generate a new pairing phrase). Thank you!
