MHGEN EU invalid literal for int Error

when using dnsmasq and a proxy to attempt to download the DLC for MHGEN I am getting this error.

ERROR:root:invalid literal for int() with base 10: b'{\x1b\xd8\xb1\xcc#\xe2\x8a2\n\xcf)\x08\x02\xef\xf5\x0b\xa1\xffy\xcd\x14\xf9\xb6Od\x05\xf4eo\xcf\xed(e\xa0\x13'

I am assuming this is pretendo having a different token format but I am not experienced in networking.
Any help is appreciated either with fixing this or any other methods for patching the dlc files into mhgen

Start by reproducing the failure with the MHGEN EU DLC request and trace the handler for /SSL/3ds/mhx/login_eu.cgi. Inspect how the response token is parsed and compare the observed byte value with the expected format. Done means the request no longer raises the integer-conversion error and the DLC download flow completes successfully.
