cometD Listener does not subscribe to channel after 403 Unknown Client Error

[tauqirghani]

My implementation of cometD.NetCore.Salesforce stops receiving any messaged from Salesforce channel I have subscribed to.
My observations from network are as follows:

This is the communication Pattern:
Initial call sequence
/handshake
/connect
/subscribe

This is followed by a series of /connect loops, each lasting a fixed two minutes or so
About a hundred calls later /connect gets an advice with 403: unknown client
[{"advice":{"interval":0,"reconnect":"handshake"},"channel":"/meta/connect","id":"304","error":"403::Unknown client","successful":false}]

This reponse also has an additional header, not present in earlier responses

cometD then initiates /handshake and gets this reponse
[{"ext":{"replay":true,"payload.format":true},"minimumVersion":"1.0","clientId":"1cyu4thyxh3fgv1nqwcvebt3o9x","supportedConnectionTypes":["long-polling"],"channel":"/meta/handshake","id":"305","version":"1.0","successful":true}]

Now cometD resumes /connect calls - the first response is unique, it has an advice
[{"clientId":"1cyu4thyxh3fgv1nqwcvebt3o9x","advice":{"interval":0,"timeout":110000,"reconnect":"retry"},"channel":"/meta/connect","id":"306","successful":true}]

HOWEVER, at this stage there is no message received on the channel from Salesforce.

Just to be clear I am using Bayeux client, not the ResilientStreamingClient.
I have added error listeners but do not receive any messages in those listeners

It appears to me that after /handshake cometD is not resubscribing to the channel.
I don't see this particular issue reported here. Is it a solved problem? Then I would love to know the solution.

Did you find a solution for this?
