The thing that finally caught my eye is the "connect: cannot assign requested address" part in the error message. You can search for it in combination with golang. I'm not exactly clear but this could be related to running out of socket or port resources, maybe in combination with changes in how many parallel HTTP requests are fired off by go mod tidy and go mod download. The overall communication/socket "load" of your system might also be a factor to look at. On Monday, May 22, 2023 at 12:04:01 PM UTC+2 Joao Miguel Ferreira wrote:
