I am using curl 8.15.0 and multi interface and everything works as expected, however at some point I see this error Connection died, tried 5 times before giving up
I would expect that should never happen, the current config I have has:

Multi (connection pool)

CURLMOPT_MAX_TOTAL_CONNECTIONS=1024
CURLMOPT_MAX_HOST_CONNECTIONS=64
CURLMOPT_MAXCONNECTS=256
CURLMOPT_MAX_CONCURRENT_STREAMS=100
CURLMOPT_PIPELINING=HTTP1|MULTIPLEX # enable HTTP/1.1 pipelining and HTTP/2 multiplexing

Easy (per transfer)

CURLOPT_DNS_CACHE_TIMEOUT=60 # seconds
CURLOPT_TCP_KEEPALIVE=1 # on
CURLOPT_TCP_KEEPIDLE=10 # seconds
CURLOPT_TCP_KEEPINTVL=5 # seconds
CURLOPT_TCP_KEEPCNT=3 # probes
CURLOPT_MAXAGE_CONN=118 # seconds
CURLOPT_CONNECTTIMEOUT=5 # seconds
CURLOPT_TCP_NODELAY=1 # on
CURLOPT_PIPEWAIT=1 # on
CURLOPT_FOLLOWLOCATION=1 # on
CURLOPT_LOW_SPEED_TIME=20 # seconds
CURLOPT_LOW_SPEED_LIMIT=100 # bytes/sec

Debug logs from the issue:
debug..txt

What i notice from this log is that we receive the GOAWAY that has last_stream=3693

• received GOAWAY, error=0, last_stream=3693
  and all the failing requests I see they have higher stream_id

I would expect libcurl to try on a new connection but seems like it doesn't?
