ipv6 - Stuck at startup trying to connect to raw.githubusercontent.com (Ubuntu)

[luxapana]

I've been using the program for a while in ubuntu 22.04 for a while without much issues. Yesterday updated the system and now fusion wont start. When started it from the terminal as below, I can see that the script is stuck in connecting to Connecting to raw.githubusercontent.com.

startup command:

export WP_BOX='/home/manusha/.fusion360/wineprefixes'
source /home/manusha/.fusion360/bin/launcher.sh

output:

update

It eventually started up very very slowly! Not usable at all. I feel this has something to do with a slowness in a low level system level API. Anyone experiencing this?

it could be an IPv6 issue. can't tell you exactly what. I've faced similar issue in the past for raw.githubusercontent.com (not related to fusion 360 BTW). it occurred when connecting from a particular network behind a firewall, and whenever I change my network it works seamlessly. so I've concluded its an issue arising from the FW when handling IPv6 traffic.it could be anything from DNS, IPv6 routing, or IPv4/6 translation or something else.

However, 1 main difference between my problem and yours is that it always timed out for me and I couldn't connect. If you suspect its a problem from your network or that your are behind a firewall then its worth trying another one and test.

sorry, can't help you further.

Try to disable ipv6 which on my case it helped. On Ubuntu:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1
