Merge replication not working (Push or Pull)

I'm trying to setup merge replication between two server (serverA and serverB). serverA houses the publisher DB (pubs) and Distribution DB (distribution), server B has the subscriber DB (subs). I tried first to setup a pull subscription, but the snapshot is never created in the subs db, even though the snapshot agent says everything was successful. The merge agent also never changes from the status 'Never Started'.
So I tried a push subscription. This gets me a little further, it creates the snapshot in the subs DB, but then the merge agent fails with the following error.
The subscription to publication 'pubs_customer_test' is invalid.
(Source: Merge Replication Provider (Agent); Error number: -2147201019)
------
The remote server is not defined as a subscription server.
(Source: BBLABCW03 (Data source); Error number: 14010)
------
Please help. Thanks.After creating a pull subscription to a transactional Publication, the status
of the pull subscription in the Database -> Pull Subscription Folder will
never change from the default of 'Never Started'
The job and the Pull Subscription Agent will show history for the agent, but
the status does not change in this view.
The problem is that the name of the job is greater than 100 characters, and is
trying to be placed into a temporary table that only allows 100 characters for
the job name.
SELECT job_id
FROM msdb.dbo.sysjobs
WHERE (name = N'SQL02-MyProj-DBReplication-SQL01-RptDB-D3E11F67-B38E-4DE4-82AE-9A3358B902AF')
-- Get job ID
-- Run below command with the job id as input
sp_MSenum_replication_job @.job_id = '388BFC85-BB28-434F-A7AE-77EEBB1A3C8B'
-- If you see this error, then you may need to reduce the -- job description name to resolve this issue
Server: Msg 8152, Level 16, State 6, Procedure sp_help_jobhistory, Line 91
String or binary data would be truncated.
NOTE: Then name of the job is a automatically concatenated by SQL of the
Publishing Server Name + Publishing Database + Publication Name + Subscribing Server + Subscribing Database.
