Cannot select DoH server on archlinux

[maz-1]

error message:

Traceback (most recent call last):
  File "accesser.py", line 303, in <module>
    DoH.init().run_forever()
  File "/opt/Accesser/utils/DoH.py", line 136, in init
    logger.info('Auto selected DoH server: '+DoH_domain)
TypeError: can only concatenate str (not "NoneType") to str

I added

    except Exception as e:
        print(e)

to line 113 of utils/DoH.py, And the exception info I get is
The NPN extension requires OpenSSL 1.0.1 or later.

According to a similar issue(HENNGE/aapns#10), the openssl libray provided by system may not have npn support enabled

Same TypeError here. Ubuntu 18

But I have just tested it on Ubuntu 18.04 (with python3.7.3 and Firefox) and it worked well.

You can check if the exception in line 113 is The NPN extension requires OpenSSL 1.0.1 or later.

You're right. In fact openssl version is 1.1.1b, so it's same bug with maz-1

For the same reason as #10, it will not be fixed.

You can use dnscrypt-proxy temporarily.
