Tableau Prep Builder cannot connect to tabpy server with https

[Rahovski]

• OS: Ubuntu 18.04.5 LTS
  • Python version: 3.6.9
  • TabPy release: 2.3.1

Describe the issue When i used in Tableau prep builder https connection to tabpy server, then requests fail. With http tabpy server worked correct (address:port) But when i use https connection ( https://address:port), then i don't see any requests in debug's log. But if i open this address in browser, i see, that server is working correct

To Reproduce

1. Create x509 certificate in pem code(default) openssl genrsa -aes256 -out prk.key 2048 openssl req -new -key prk.key -out tabpy_cert_req.csr openssl x509 -req -in tabpy_cert_req.csr -signkey prk.key -out tabpy_cert_req.crt sudo cp tabpy_cert_req.crt /usr/local/share/ca-certificates/ sudo update-ca-certificates
2. Change tabpy config file

   [TabPy]
   TABPY_PORT = 49140
   TABPY_TRANSFER_PROTOCOL = https
   TABPY_CERTIFICATE_FILE = /home/tableauBeta2020/tabpy_dir/tabpy_sec/tabpy_cert_req.crt
   TABPY_KEY_FILE = /home/tableauBeta2020/tabpy_dir/tabpy_sec/prk.key
   TABPY_LOG_DETAILS = true
   TABPY_EVALUATE_TIMEOUT = 90

3. Start tabpy in venv tabpy --config=/home/tableauBeta2020/tabpy_dir/conf_tab_py.conf Start_log: log_debug_after_Start_server.txt
4. Downloaded certificate to desktop
5. Make connection with https

Expected behavior It was expected that after opening the page with https request, it will be possible to create a connection tableau prep builder with tabpy.

Finded a solution. Need was write correct Common Name (e.g. server FQDN or YOUR name), when i was signing a certificate. Common Name (e.g. server FQDN or YOUR name) [] : ip-address
