I also tried atvremote wizard, the error logs are similar to above. Maybe OverflowError: Data too long. Max 2**32 bytes is the problem? Please help on this. Thanks a lot.

Hi and sorry for the delay! I just want to confirm if you still see this issue?

JoechiaoPshan commented 6 months ago

Hi, thanks for the reply. I just tested on 0.14.5 and the issue was still the same.

postlund commented 6 months ago

Would you be comfortable with modifying the source a bit? I would like to see the encoded TLV value around here:

https://github.com/postlund/pyatv/blob/2f7e2fd1b30e75f490171e0cb2a10592afba2546/pyatv/auth/hap_srp.py#L201

Adding something like this would be fine:

print(write_tlv(tlv))

Here's the output value.

postlund commented 6 months ago

This doesn't make sense to me, that shouldn't be a problem. Can't you also add this:

print("length:", len(data))

here:

https://github.com/postlund/pyatv/blob/2f7e2fd1b30e75f490171e0cb2a10592afba2546/pyatv/support/chacha20.py#L48

Do you see any absurdly large lengths?

JoechiaoPshan commented 6 months ago

length: 152

It wasn't too large I suppose?

postlund commented 6 months ago

Nah, limit is 4GB (2^32). Suspecting either issues with encryption library or bug in python. Would it be possible for you to try with another/newer python version?

JoechiaoPshan commented 6 months ago

I'll try with other python version and report the result here later, thanks for the help!

postlund commented 6 months ago

Thanks for your quick help, let's hope we get good closure on this!
