Looking for some help figuring out what's going on with this pcap.

IP addresses in question: (client) & (server)

Client is having issues downloading a csv file from the server. Other clients on the network do not have any issues. The behavior in the browser is that the download will progress either only a few KB or maybe get to 75%, but eventually will just hang forever.
The server is a single board computer running slightly a customized Linux distribution (Debian based I think). I do not have much visibility or access to the server, and I think it is running the Node-RED web server.
Clients are all Windows 10 Pro 22H2 fully patched.

Thank you in advance for any help, Chris
