is that Zerops subdomain or your own domain?

minsomaiOP•4mo ago

our own

Hi @minsomai, the default nginx settings are:

 
client_header_buffer_size 1k;
large_client_header_buffers 4 8k;

 
client_header_buffer_size 1k;
large_client_header_buffers 4 8k;

It's not currently possible to change the configuration. However, it will be possible to change the nginx settings soon.

What values would your application need?

its showing 11KB ^ @Jan Saidl we might need more If I host in ubuntu instaead of nodejs service, I can configure this myself?

Jan Saidl•4mo ago

No, switching to Ubuntu won't help. This is a configuration limitation of Nginx, which is at the project's entry point. I'll try to manually change it on your project now to see if it helps. If it does, I'll try to come up with a permanent solution. I set it to 16k instead of 8k, can you please try it?

client_header_buffer_size 1k;
large_client_header_buffers 4 16k;

client_header_buffer_size 1k;
large_client_header_buffers 4 16k;

nop not working

Jan Saidl•4mo ago

All right, another try:

client_header_buffer_size 16k;
large_client_header_buffers 4 16k;

client_header_buffer_size 16k;
large_client_header_buffers 4 16k;

minsomaiOP•4mo ago

nop

Jan Saidl•4mo ago

I can see it in the log. Okay, so I've set really big values. Can you try it now, please?

    client_header_buffer_size 52k;
    large_client_header_buffers 4 52k;

    client_header_buffer_size 52k;
    large_client_header_buffers 4 52k;

minsomaiOP•4mo ago

nop. I can DM you curl, LMK

Jan Saidl•4mo ago

Yes please Hi @minsomai , after some experimentation I think that the correct values will solve this problem. I am currently working on a solution that will allow you to set this on your project.

thank you @Jan Saidl looking forward to it

Hi @minsomai we finally released a new feature and now you can customize the l7 balancer configuration. Unfortunately the frontend is not ready yet, but you can make the change via API. After the change, you still need to make any change in http routing - for example enable subdomain. If there is any problem I can do the setup for you.

# read current configuration
