this sounds like somebody messed up or something else needs updating.

you should go yell at the nginxproxymanager people. :wink:


Hi @Caicaiziya, and welcome to the LE community forum :slight_smile:

Maybe we should see that log file.


i can't find anything else in the log file.

that l in list, it needs to be uppercased.

It's a bug in certbot_dns_tencentcloud

NB: both list and dict need to be lowercased in python 3.9


Don't forget to import it from typing :wink:


thanks for your help.
but i change "l" in certbot_tencentcloud_plugins.py(line 251),and try it again.

An unexpected error occurred:
NameError: name 'List' is not defined

so i still can't slove the problem.and I don't know how to continue.plz tell me about more details. :wink:

oops,i can't understand what u mean.
plz tell me how to fix it.
I appreciate it.

At the top of the file you just modified there's also:

from typing import Dict

You should change that to:

from typing import Dict,List

Oh dear,i delete "list",and it works.

change line 251
def describe_record_list(self, domain: str) -> list[Dict]:
def describe_record_list(self, domain: str) -> [Dict]:

Yeah, type hinting isn't actually required for the actual working of the code. I think, if you're removing the type hinting partly, you can better remove it entirely:

def describe_record_list(self, domain: str):

oh i just used it on my selfhost,i don't understand a lot of programing.so,i'll keep it if it still works.
i don't konw what this mean. (-> [Dict])

It's for type hinting. It's not necessary for the proper functioning of the code itself.

I've suggested the fix upstream:
