Describe the problem

I'm running FreshRSS locally using xampp, just for personal use. I've been using it for a while now with Reddit feeds, using the old.reddit.com subdomain as suggested by some other troubleshooting posts. Occasionally, I will get a spate of 403 errors with all Reddit feeds, which can last anywhere from minutes to days. (Possibly until my IP refreshes or something changes on Reddit's end? This issue is so inconsistent that it temporarily resolved itself while I wrote this report.)

Last time this happened, I found that sending a custom useragent seemed to resolve the issue. Recently, I'm experiencing issues again. What's stumping me though is that while this issue is occurring, using curl and sending a custom useragent via the command line works fine, and I can download the RSS feed, indicating that I'm not rate-limited by IP or something. Running on the command line without a useragent or using FreshRSS with a useragent results in a 403. Is FreshRSS not properly sending the useragent? I have also ensured that I'm testing with the curl executable that FreshRSS is likely to be using (the one included with my xampp installation).

Example command which works via the command line:

curl -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:144.0) Gecko/20100101 Firefox/144.0" https://old.reddit.com/r/worldnews.rss > test.txt

Is there a way to see in detail what FreshRSS is doing with curl behind the scenes and identify what's going awry?
