otcv8 json error 1fc0

[Joriku]

So, I'm lost and can't find anything anywhere related to this issue.
So I am getting this once I set things up.


I am running a Virtual Box,
192.168.10.213



updater.php

So, I'm lost and can't find anything anywhere related to this issue.

I got 2 ideas:
1. remove ?> at end of PHP files
2. make sure that all PHP files are encoded with Unix/Linux line endings (LF character), not Windows line endings (CRLF - 2 characters)

If they do not help, then we got to get result of Virtual box information.
Execute:

curl -X POST -H "Content-Type: application/json" -o output.txt -d '{}' http://192.168.10.213/otcv8/updater.php

and post output.txt as file attachment on OTLand.
Error says something about 1fc0, so maybe there is this value somewhere in PHP response and we can find out why it's formatted wrong in JSON.

1) Removed ?> from updater.php, results in the same.

2)

IDK why OTC gets this 1fc0, but it looks like it's added at start of JSON. output.txt does not contain it, so it must be something with updater code in OTC or JSON library in OTC.
You will have to add some code in updater module/JSON library to print received JSON and detect where it adds 1fc0.

So I did this instead after a friends tips.

GitHub - OTCv8/otclientv8: Clean, ready to use version of OTClientV8 - Alternative, highly optimized Tibia client

Clean, ready to use version of OTClientV8 - Alternative, highly optimized Tibia client - OTCv8/otclientv8

github.com

Using this, made an update possible with the same steps as the tutorial explained it.
I have not tried out using the dev packages to compile it, in case of source edits. But this works for now.

Then, the desp says (by image):


Thank you Gesior for responding to the thread, really appreciated.

And to note for others:
No, I did not have to change anything extra for this step to work, and the updater works locally and through an host machine (live).
I've updated the client a few times, and it works.

GL and DX seems to respond fine.
