Wrong default network settings (MTU) of my client affects if I can reach fly.io

[kb1]

http connects, but no request on the machines

My App behaves weirdly. When I manage to visit the page once successfully, then I can use it just as usual. And this is not cached. I generate log entries with every hit. But when I want to shift-reload, use a private window or try a wget from the Terminal, then I have issues. It loads forever. The Browser then timeouts. The wget on the Terminal stays in the same state for minutes before I kill it. ➜ wget https://v1company.6week.space/cycles/2/building --2023-07-18 14:42:52-- https://v1comp…

So I could not stop thinking about this issue and why it was only happening with my ISP at home.

I looked for help in a subreddit for my router. And it turned out that I needed to change the MTU size of my network device.

I wonder… I have been with this connection for five years and with my new router for a couple of months. And it never happened to me with any other side.

So I wonder if this is something that needs fixing by fly.io. If I remember correctly, they operate their own data centers.

I am really worried about building my next startup on the infrastructure of fly.io, because also others could be victims of the same issue.
