Connection Error

[bpkum]

I am trying to get the bars data in a loop, once every 5 mins... It looks like I have exceeded the max retries... Initially, I was just doing it in a loop (without the 5 mins spacing), it worked fine for a few days, but then I started getting this error... so I spaced the get bars 5 mins apart...but now it fails as soon as I do the first get bars call (even with the 5 mins spacing)... Any help?

Any help?

The error indicates a network issue. I'd start by opening a couple cmd windows and ping your default gateway in one and the quotes-gw.webullbroker.com site in another. When your script fails, check if you are also dropping ICMP and where. If you really want to understand the network error and who is causing it, then you may need to use Wireshark and look at the raw network traffic.

Fantastic recommendation.... I was thinking this was an issue in the code or webull was just blocking my IP address... but it turned out to be a broken router... reset my router... looks to be working fine now... thanks again for the advice... @alexonab
