struggling here...
I can easily get rtk2go corrections albeit too far away on my postcard using the firmware ntrip client.
When I try to use the Australian government Auscorrs site, sw maps gets great corrections data on port 2101. If i manually enter the exact same credentials into the NTRIP client on the RTK postcard i get a connection refusal. I would rather not rebuild this part of the RTK anywhere firmware as it creates an orphan fork. it seems there may be an issue in formulation of the request. I will try to get a log when I have sky view later today.
It's only an orphan if you don't get the changes pushed back to the main repo.
Run tcpdump on your router and look at the SYN packet and check address/port.
I am not using a router. Running it directly off my phone hotspot but will
try to do a trace some other way.

v3.3 Postcard + AUSCORS is working fine for me this morning.

Here are some things to do and check:
* For debugging, turn on correction debugging. This will show you when RTCM is received as well as print additional messages during failed connections: <img width="622" height="449" alt="Image" src="https://github.com/user-attachments/assets/7533abed-dea9-4a65-b9fb-c385ca7ef9d9" />
* Double check that you have the user/pw correct, the caster address correct, mountpoint entered, and GGA enabled: <img width="909" height="332" alt="Image" src="https://github.com/user-attachments/assets/e8dfb3ca-f722-43a5-a953-d42513acf4db" />
When I copy/pasted the caster address from the AUSCORS website it picked up an invisible tab in front of 'ntrip.'. Perhaps you are getting similar whitespace issues.
Let us know if you continue to have issues.
