We are facing an issue in TYK v4.3.4 while using an streaming API where the API executes for 4-5 minutes. We already have timeouts configured at 10 minutes.
But on hitting the API it is giving below error in client response: Error in the HTTP2 framing layer
We also tried to lower down the HTTP2 to HTTP1.1 (using enable_http2: false) version, but then error changed to below: curl: (56) OpenSSL SSL_read: error:1408F119:SSL routines:ssl3_get_record:decryption failed or bad record mac, errno 0
Can anyone please check if we are missing any configuration in v4.3.4 as in v2.5.1 same API works normally.
This is blocking us to upgrade, so need urgent support.
This would mean its not occurring at random or after a number of requests?
What is the flow of the request? I assume hitting the upstream works as expected.
This error was coming when we were trying to download data above 80-90 mb in size. till 70-80 mb API is working fine. With upstream URL, all APIs were success with data up to 500 mb.
Also how are the certs generated?
Currently we have self signed certificated generated & configured.
Today we have made below changes in our tyk.conf, that resolved the issue for now:
only proxy_default_timeout was changed from 600 to 1200, others confs added newly.
are these configurations looks OK & recommended for streaming API use cases (where 300-500 mb data is being transferred).
Also on removing enable_http2 conf also we see HTTP1.1 request, is that OK.
