hi all,

We are getting 408 request timeout for our SUBSCRIBE method inspite of other Useragent sending
a 200OK response for the SUBSCRIBE method.

Both SUBSCRIBE and 200OK packets are getting proxied to respective user agents correctly.
But the client1 is receiving 408 request time out error and the client2 is receiving SUBSCRIBE methods often.

The SUBSCRIBE packet and the 200OK packet are as shown below.
