hi,

long time fan of SignTools.

In the last few months, I've been unable to sign any apps, with the message "ERR_LOCK_TIMEOUT: failed to acquire lock before timeout" appearing in my nginx logs, signtools docker container, and mac builder.

I've tried several different apps and different browsers to upload different IPAs for testing, as well as trying to use a URL instead of uploading directly to the Web GUI.

Additionally, I've tried to add the below in my NGINX Proxy Manager advanced settings (and subsequently only uploading apps up to ~250MB), and there is still no luck.

proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 36000s;
proxy_connect_timeout 36000s;
proxy_send_timeout 36000s;
proxy_request_buffering off;
client_body_buffer_size 300M;
client_max_body_size 300M;

Would really appreciate anyone's help on solving this one.

Additionally, I don't think this is an issue with my nginx in particular, as i have a few other services running behind the same proxy manager, and they can upload files of any size.
