Hi. Im trying to use uplink in Anvil
but im getting this error:

Connecting to wss://anvil.works/uplink
Traceback (most recent call last):
  File "XXXXXXXXX/main.py", line 49, in <module>
    anvil.server.connect("server_XXXXXXXXXXXXXXXXXXXXXX")

    self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1000)

This is the code im trying to connect

import anvil.server
anvil.server.connect("server_XXXXXXXXXXXXXXXXXXXXXXXX")
anvil.server.wait_forever()

some help would be greatly appreciated, thanks guys

What version of uplink? If its less than 5.0 then pip install anvil-uplink --upgrade

If that is not it, then you might need to run it with python 3.11 or less because of an ssl library incompatibility with 3.12
