"Upload failed. PHP post_max_size is to small" even after changing nginx.conf about lychee-docker

[d7415]

Hi. Did you also update the line
client_max_body_size 100M;
in the nginx config? It may also be worth checking any upstream reverse proxies/etc.

I remember thinking in the past that that error needs changing, but I haven't done it yet.
The actual error is

Upload failed. The PHP post_max_size may be too small! Otherwise check the FAQ.

so is correct.

Hi, thanks for your answer.
I already changed the client_max_body_size to match the wanted post size (500 MB).
However, I did not check the upstream reverse-proxies.

My server is behind Cloudflare and I use HAProxy for my reverse-proxies.
I found that HAProxy has no limit in upload. I searched a bit more and found that Cloudflare is limiting uploads to 100 MB for free and pro plans.

Thanks for your help again, I would not have thought of the reverse-proxies.

Ah, good to know. Glad to help!

I had the exact same issue - running the latest docker image and
also have adjusted the nginx.conf file as per the documentation
but I was still getting

Upload failed. The PHP post_max_size may be too small! Otherwise check the FAQ.

I just wanted to confirm the culprit was indeed a reverse proxy, in
this case it was nginx running in another docker container, since
it has the default upload limit set to 1M.

Setting

http {
  ...
  client_max_body_size 100M;
  ...
}

in the reverse-proxy config fixed the issue (could also be set in the
server { .. } section for single app).

Just wanted to mention that, hoping it helps someone else too!
