The data length of the http2 message exceeds 65526 and later will be discarded

We then pass the data through http 2.0 in plaintext, the data length of http2 messages exceeding 65526 will be partially discarded, resulting in incomplete data and affecting normal operations.
Currently, the solution is to turn off the HTTP 2.0 checks, not to do checks on HTTP 2.0, and the business is back to normal.
May I ask if anyone has encountered such a situation? Do we have a limit on the length of data for http 2.0? I have a packet here that reproduces the failure site by playback as well.

Hi @jianghxa ,

I would recommend reaching out to support with the pcaps. Support should be able to do a tcpreplay to confirm the behaviour and analyse further.

Cheers,
