failed to fetch 2.0

[calm creek]

i was getting this error (view the screenshot 1)
I added <meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
And now i get this:

my app runs on remote linux server. Frontend runs on nginx and backend is a java app

i am lost. What to do in that situation?

[safe oyster]

Enable HTTPS?

[calm creek]

i enabled it

[calm creek]

with this

i changed my rul several times:
https
http
domain instead of localhost
ip of server instead of localhost
Tried to add meta tag
Nothing worked

[safe oyster]

dafaq? enabling https has nothing to do with meta tags

[calm creek]

then what do you mean?

And can i ask you to answer to messages, so i can get pinged

[safe oyster]

enable HTTPS on your server and point to that URL. stop attempting to use HTTP for the API

with what little information you provided, it sure sounds like you should be able to just set up an nginx reverse proxy for the API routes

[calm creek]

"enable HTTPS on your server" on remote server?

[safe oyster]

The API server (as I said)

[calm creek]

my API server is java spring boot app and it accepts https requests

[safe oyster]

Then stop sending HTTP requests…

[calm creek]

I changed to https

but nothing changed

look

[safe oyster]

Clearly your API server is not accepting HTTPS connections on port 8080

[calm creek]

I tried to make request with curl from terminal of remote server

and it worked

[safe oyster]

congrats

[calm creek]

thanks, but i still get the error

it only means, that backend is fine

and problem is with frontend

[safe oyster]

not necessarily

[calm creek]

maybe nginx

[calm creek]

explain please

[safe oyster]

all sorts of things on the backend could allow local connections but not remote connections (firewalls, nginx configs, etc.). what is behind the red line?

if it's localhost or 127.0.0.1, that's possibly your issue. if not, nginx is probably not configured to handle whatever host/port it is

[calm creek]

IP of server

[safe oyster]

that's meaningless. it could be a LAN IP or a localhost IP, which wouldn't be accessible from elsewhere

[calm creek]

i mean IP of remote server

[safe oyster]

...

[calm creek]

[calm creek]

so what do you suggest to do?

[calm creek]

So i tried to configure nginx, but maybe something is missing. What config should i check?

[calm creek]

I figured it out

lmao

thanks for help, mr ironic

but now i have new errors😁

[safe oyster]

not sure what part of my comments would be ironic, but okay
