it is probably textastic compressing the file... I am no professional on this topic, but this seems the most likely reason.
It is now working on my home wifi... Probably some weird bug or network outage or something.

If anyone else has this same problem, i would probably try resetting your wifi...
There is no firewall on the network to my knowledge.

The test I ran with FileZilla was on the same wifi network...

Edit: I tested it on another wifi network and it seems to be working fine now...

my main concern is if I wil be able to reconnect with my home network.

I have also deleted and reinstalled the textastic app, same issue...


I did manage to collect some logs though...

Here is the contents of the log file (square bracket censorship mine):
