what need to change

[scaramallion]

Next time could you post a minimal code sample + output, especially one without threading? Having dozens of the overlapping versions of the same error is really hard to parse and is just a pain, for me and anyone else looking at the same issue for help.

The (excessive, I should fix that) UID warnings are because pydicom v3.0 doesn't have the newer transfer syntaxes. You can fix that by removing them from ALL_TRANSFER_SYNTAXES upgrading to v3.0.4.

As for the exceptions, looks like there's a text value in the association request that doesn't use the required ASCII encoding. Probably an AE title. It's always an AE title:

ValueError: Unable to decode 'C0 33 8E 79 F8 7F 20 20 20 20 20 20 20 20 20 20' using the ascii codec(s)

>>> b = b"\xC0\x33\x8E\x79\xF8\x7F\x20\x20\x20\x20\x20\x20\x20\x20\x20\x20"
>>> b.decode("ascii")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc0 in position 0: ordinal not in range(128)
>>> b.decode("utf-16")  # probably not correct since 0x20 should be the padding spaces, you can figure out the right one
'㏀禎翸†††††'

Although maybe it's doing a weird mix of allowing non-ASCII AE titles then padding them out with ASCII spaces? Gross.

Anyway, this can be worked around by extending the encodings list via _config.CODECS or fixed permanently by finding the non-conformant value (have you checked the AE title?) and make it conformant.

I feel like we've had this discussion before.

If that doesn't work can you post the output from:

from pynetdicom import AE, evt, debug_logger
from pynetdicom.sop_class import Verification, USImageStorage
from pynetdicom._handlers import debug_data

debug_logger()

# Create AE, add handler to server as normal
ae = AE(ae_title="Dicom")
ae.add_supported_context(Verification)
ae.add_supported_context(USImageStorage)

# DO NOT USE THREADING OR I WILL DIE
ae.start_server(("192.168.1.10", 11116), evt_handlers=[(evt.EVT_DATA_RECV, debug_data, [0x01])])

And then send a single C-STORE request. This will at least let me narrow it down to the AE title.

[scaramallion]

The (excessive, I should fix that) UID warnings

Ideally I'd be able to register the transfer syntaxes using register_transfer_syntax(), but I don't think that would actually work for a public transfer syntax. Patching the module is probably the "best" way to do it.

Edit: No, that doesn't work because UID.is_transfer_syntax does a lookup against the UID dict. So it'd need to be added to the dict. But there's no public method for that...

File "C:\Users\Admin\AppData\Local\Programs\Python\Python313\Lib\site-packages\pynetdicom\pdu.py", line 581, in calling_ae_title

Oh, I missed this the first time due to all the threading nonsense. It's definitely an AE title that's the problem.

Thanks for you time and reply I will try and will let you know
