Using ubuntu16.04. virtual_env version = 15.1.0. The setup instructions all seemed to install fine with no warnings. When i try to login to the webpage it fails. I signed the message as described, then pasted it to the box. then i get the Rendezvous error.

I had the same issue, this pull request (https://github.com/lightninglabs/lightning-coindesk/pull/3) fixes the problem. Also one has to be aware, that if one generates the certificate by hand from tutorial 2 it is not compatible with the grpc via python from tutorial 3. To make it work, just delete the tls files and let lnd generate them.

Running into the same issue and lightninglabs/lightning-coindesk#3 doesn't fix the problem. Also deleted the tls files. Traceback: http://dpaste.com/1MA7D2Y

@karanv Same here. I tried the pull request unsuccessfully. Also, @bitromortac I deleted tls.cert and tls.key from $HOME/Library/Application\ Support/Lnd and it did not change anything. Since this appears to be a gRPC issue of some sort, here are the relevant dependencies I am running on:

googleapis-common-protos (1.5.3) grpcio (1.10.0) grpcio-tools (1.10.0) python (2.7.10)

[ccdle12]

Having the same issues and tried https://github.com/lightninglabs/lightning-coindesk/pull/3 and deleting tls.cert and tls.key.

Doesn't seem to have resolved the issue

[blockchainsolutionshi]

Tried deleting tls.cert and key but still having this problem.

Any ideas?

[LNMultiplayer]

I am running into this same issue with the exact same Rendezvous error and trackback. Has anybody found a solution?

[wielandgmeiner]

Running into the same issue, the mentioned PR doesn't solve the problem, recreating the tls.cert through lnd neither. Solution anyone?

[SkyHustle]

Having the same exact issue. Anyone figured out a solution?
