Unexpected client/server version mismatch

[ramiromagno]

I have remoter version 0.3.2 installed on two machines, the same version 0.3.2 on both, but when I try to connect from one to the other I get client/server version mismatch; client kicked. on the server side and Error in remoter_check_version_local() : Incompatible package versions; quitting client (perhaps you need to update and restart the server?) on the client side.

I have installed remoter in the same way, i.e. with install.packages("remoter", dependencies=TRUE) on both machines.

Hi, thanks for the report. I think this has been fixed in the latest version here on GitHub.

I'm hoping to get an update out to CRAN "soon", but there are some complications. Optimistically, we should have the new version on CRAN in about a week. In the meantime, if you can, I'd encourage you to install the GitHub version of remoter.

I have remoter version 0.4-0 installed on two machines, but when I try to connect from one to the other I get

[2018-05-28 18:24:04]: client attempting to connect...
[2018-05-28 18:24:04]: client password authenticated
[2018-05-28 18:24:04]: client/server version mismatch; client kicked.

on the server side and

Error in remoter_check_version_local() : 
  Incompatible package versions; quitting client (perhaps you need to update and restart the server?)

on the client side.

I also have installed remoter in the same way, i.e. with install.packages("remoter", dependencies=T) on both machines.

Sorry for the delay. Work has had me at more than 100% capacity.

I haven't had a chance to take a close look (I plan to tomorrow), but I'm guessing the checker is throwing the error because of the differing pbdZMQ versions. I will double check but I think for those two pbdZMQ versions, it should work (making it a remoter bug).

I am getting this error, too.

Client: R=3.6.1, remoter_0.4-0, pbdZMQ_0.3-3 Server: R=4.0.2, remoter_0.4-0, pbdZMQ_0.3-3.1

What other diagnostic steps can be taken?

(This actually used to work previously (3.6.1 <-> 4.0.2), so obviously something has changed but the error messages do not give enough information to find out what's going wrong. Anything else I can try?
