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 11 months ago

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

postlund commented 11 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 11 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 11 months ago

length: 152

It wasn't too large I suppose?

postlund commented 11 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 11 months ago

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

postlund commented 11 months ago

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