I shall try putting a proxy in front of it in due course.

"Later on, mono fixed whatever bug caused it."

Do you plan to release a version with the fixed mono libraries anytime soon?

Either way, thanks for your help so far.

@atripp Good to know that netcore is in the pipeline.

Regarding using nginx, not exactly sure how this would help with Mono's network handling.
I have the containerised instance in AWS, and SSL offloading is being handled by an Elastic Load Balancer.
If I have nginx between the ELB and the proget container, surely it is just going to pass the connections straight through, unless it is configured to cache as well?

Hi,
Do you have any links to people using nginx reverse-proxy setups?
We did have it running on Windows, but moved it to docker to simplify upgrades - i.e. less downtime.

Are there any plans in future for proget to become a native .net standard application and therefore not require mono?

Hi,
I am fairly regularly getting the following exception
Source may be either web application or GET request to feed.

Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
