Stack overflow while reading xml about tinyupnp HOT 4 CLOSED

I commented out the debugPrint(line) on line 707, in getIGDEventURLs().
But don't worry, I realise your serial baud rate is at 115200 while mine is at 9600. Once I pumped up the baud rate it solved the issue. Likely what I suspect the code run faster then serial print can chuck out and overflow the stack in memory.

May want to put a note to in readme as it is gonna be an issue as xml response can be huge at time and quickly clogging the serial port during debug.

(p.s. i was going to post another issue saying I have a 501 error after sending Addportmapping to IGD, but after spending 4 hours playing with the SOAP request that sent to IGD, thinking that was the issue, finally realise the real issue is I cannot do port forwarding behind mobile 3G/4G network, as the infrastructure is basically behind another commercial grade NAT on the provider side. In other hand, I have no Public IPv4 IP to start with. Though addportmapping function exists with the WANPPPCONNECTION:1 service available by my router (even listed on the xml), it simply is disabled and return error 501 - action failed when tried)

Weird...I just made a change and comment the line to debugPrint(line), and no more error for that.... I don't know enough how serial print works... maybe the serial print bottleneck it and force it to store more line than needed, causing the stack overflow?

Could be a memory capacity issue?
Can you point me to the exact line where it happened? The one you commented out.

Also, be aware that you can disable all prints using a flag in the .h file. Simply commenting this line should do the trick.

Thanks for the information and being thorough.
Indeed, cellular companies hide you behind a Large Scale NAT and will not allow port forwarding.
Sometimes non cellular companies will do that too, and in most cases you can request them to stop, but with cellular it's a different story.
There are ways around it with VPN setups but I have no experience with that.
I will place a line about the baud rate, might help somebody.
Thanks!
