i'd focus on nginx or whatever azure infra you have between nginx and the client.
on second thought if direct request to api server works while reverse proxy fails, this points us only to nginx.
I did.
I am now redeploying to new container to be sure.
one thing I can think of is nginx default client_max_body_size
limit
None
800KB is about 1MiB
can you try altering nginx configuration in the running web instance and reload the new config?nginx -s reload
the weird things is if it's a Azure ACA issue, it would be known right ? There are so many people who use ACA and having ACA talking to each other.
this is really weird ...
Deployed fresh new and ran nginx -T in the container:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

(same issue btw)
and I tried the curl against the web url: and it fails 8/10
can you make sure the change to client_max_body_size was applied with nginx -T ?
@<1523703436166565888:profile|DeterminedCrab71> Thansk for the suggestion. But no effect.
We already have client_max_body_size 0; in the server section
I tried to set both http and server section 100M but nothing changes.
Do you think the gzip be related ?
will send the nginx -T results once the container is deployed
@<1523703436166565888:profile|DeterminedCrab71> Found the solution:
We needed proxy_set_header Connection ""; in the location /api section. Putting it above in the server section had no effect
can you try running the curl request from within the web container?
yes, I did try that exactly: all curl request succeed
yes thanks, that would be very helpful
