Mqttnet: Managed Client 2.60 not connecting

[MelangeF3A]

When I install 2.60 the Managed Client does not connect. Works OK with 2.53.

Do I need to change any connect options..?

Did you build your client with TLS without any parameters?
Because i had the same issue and it worked fine when i removed the TLS Option.

Have not been able to test the client with actual certificates, but just WithTLS() does not seem to work anymore.

Hi.

Yes that worked.. Thank You.

Hi,
I've got the same problem. I allready removed the WithTLS() option.
But ManagedClient is NOT connecting if I use the option WithCleanSession(false).
If I set the option to .WithCleanSession(true) the client is connecting.

Any idea?

Thanks...

@Katamato Hello, I also have the same problem, you can use v2.53 connection, but the client will not be able to connect if it is upgraded to v.2.60.

@pengxiaobo123 Hi, I made some tests and looked into the source code. The managed client does not support existing sessions. An UnsupportedException is thrown if the option is set. In my test client I had no exception handling... so I missed the exception.

The exception is new in Version 2.6.0 because (at the moment) existing sessions are not supported when using the ManagedClient.

Also the Options builder has some bugs with TLS related settings. So it "worked" but the internal options were wrong.

Hi,

Will it ever be possible to use existing sessions on the ManagedClient?
Or can you explain the reason why it's not supported?

We need these in one of our mqtt configurations (missed messages need to be processed after an application crash). For now we use the 'normal' mqtt client and had to build our own reconnection logic. Of course, we would like to use the ManagedClient.

Thanks

Hi,
at the moment this is not planned. The problem is dealing with the subscription management.
Best regards

Hi,
at the moment this is not planned. Because the client maintains the subscriptions and subscribes automatically even if the connection was lost. Dealing with existing sessions is a little bit complicated.

Hello, so is there by now (v3.0) any way to use non-clean connections with managed client?
Thank you!
