Could you post your code that produces the exception above, please? And if possible the output from:
from pynetdicom import AE, debug_logger
from pynetdicom import _config
from pynetdicom.sop_class import Verification
def my_validator(value):
print(f"AE: '{value}'")
enc = [f"{x:02X}" for x in value.encode("ascii")]
print(f"Encoded AE: {' '.join(enc)}")
return (True, "")
_config.VALIDATORS['AE'] = my_validator
debug_logger()
ae = AE()
ae.add_requested_context(Verification)
assoc = ae.associate("ip addr", port) # fill in your actual values
if assoc.is_established:
status = assoc.send_c_echo()
assoc.release()
And maybe try with v2.1.1, there was a fix for testing reserved A-ASSOCIATE-AC values.
I have to say that the above problems do not always occur, which also makes me confused.
These are my code:

_associate.check_status(status, StoreSCUError, "Store SCU")
except Exception:

These are the outputs of your code: why do not you use ae_title when you use associate to connect ?

Can you test with v2.1.1? The exception is coming from incorrectly checking the values for the reserved Called AE Title parameter which got fixed in 2.1.0.
I solved the character problem by using the link in the way, but occasionally this error occurs. That link is: here
environment: Linux-5.3.0-64-generic-x86_64-with-glibc2.27 Python 3.11.5 (main, Dec 22 2023, 06:42:28) [GCC 7.5.0] pydicom 2.4.2 pynetdicom 2.0.2
I'd like to know if there's any way to solve this problem or avoid it.
