I runned production server on my vps
And domain rewrites and proxy are by cloudflare
But sometimes when i refresh page , it return 502 , and when i refresh again , it will show website
What's its problem?
As i have an interval of getting user spotify connection , now its facing 502 and wont fetch that

Any ideas??
Also i got a hint
I splitted api connection to one FastAPI with an subdomain
And another next.js api routes , it successfully do calls to FastAPI but it wont do calls to next.js api through vps
And after a minute , it start calling but returning 502 and 504 and when i refresh page , it return 502 soundcloud

Where are you hosting the app

Someone mentioned about this

On Windows server

@West African Lion Hi, this is new the post and you can help him

Have you opened the port in your firewall

I won't be able to help with this since I've never used a windows server.
If it was Ubuntu I could've helped

Actually it was working successfully from first

Cause i have configured all rewriting and port forwarding on server

But issues started after using next.js api routes to call pg database and getting or updating data from there

I have ubuntu myself , but due to big problems with linux and its structure... 😂

Actually im planning to host app on Google cloud or AWS after it getting paid

I got another hint

I guess its from Next api routes

Each refreshes , its calling to FastAPI routes successfully

And in first refresh , it will all Next api routes ( with some errors )

But after next refreshes , it wont call them anymore...

Is there something configurations in next i didn't do?

I really won't be able to help since I haven't used a windows server

Oh

I did some more configurations on Nginx to handle data instead of suddenly timeout :

http {

    client_max_body_size 10M;
    proxy_read_timeout 300; 
    proxy_connect_timeout 300; 
    proxy_send_timeout 300;

    server {
    other things...

Still on my pc on dev it works normally each refreshes :
