How to call gen_server on a remote node?

Question

Erlang

Good day!
There are two nodes: the client is running on one, the server is running on the second. The client and server are based on otp. It is necessary to call the server module from the client. When called
rpc:server_call('server', module, res, [params]).
, it results in {error,nodedown}, although the module is started with a global name and the node is attached, calling nodes() shows it in the list. What did I miss?

Answer 1

hmm ... everything turned out to be nowhere easier ...
gen_server:call({global, module}, [params]).
