Platformio-core: Problem with OTA upload and hostname.local

[chessweb01]

I'm working with NodeMCU v1.0 and OTA firmware upload. According to the docs the upload should work with either --upload-port IP-Address or --upload-port hostname.local.

This is not the case. Using the IP-Address works without issues, using hostname.local produces the error "socket.gaierror: [Errno 11004] getaddrinfo failed".

Probably isn't a platformio issue. It seems an OS issue.

ping hostname.local works?
You are using Windows? Which Release?
If you are on Windows 7 or less have you installed "Bonjour Print Services for Windows"?

I'm on Windows 7, and I don't even know what "Bonjour Print Services for Windows" is.

ping IP-Address works, ping hostname.local doesn't. I guess you are right, it has nothing to do with platform.io.

google for "Bonjour Print Services for Windows" install and you will fix your issue.

obviously hostname.local would be what you have defined on your ArduinoOTA sketch

Well, it worked. Thanks a lot. Could you elaborate a bit on the Bonjour software and the ability to resolve hostname.local?

For windows users instead of installing the "Bonjour Print Services for Windows" a small change has to be applied to the script "espota.py" located in the folder C:\Users[windows user name].platformio\packages\tool-espotapy.
The line of code
remoteAddr=remoteAddr.replace(".local", "")
has to be added according to code snippet below on line 92.
```

Wait for a connection

remoteAddr=remoteAddr.replace(".local", "")
logging.info('Sending invitation to: %s', remoteAddr)
sock2 = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
remote_address = (remoteAddr, int(remotePort))
sent = sock2.sendto(message.encode(), remote_address)
sock2.settimeout(10)```

Previous comment not helps. But after revert to initial python script and installing Bonjour from
https://download.info.apple.com/Mac_OS_X/061-8098.20100603.gthyu/BonjourPSSetup.exe
It works!
Problem was on Win7 Pro and Sloeber IDE (not platformio). Default windows firewall makes no problems, can be keept running. Error message ends with following:

    sent = sock2.sendto(message.encode(), remote_address)
socket.gaierror: [Errno 11004] getaddrinfo failed
The execution of command "3.7.2-post1/python3" is done.
