Recently tried to install the ESP8266 board drivers in Arduino IDE ( version 1.8.5) using the board manager option. I get an error message that is as indicated in the attached picture. I am working in Windows 7 on a PC, the version of ESP8266 I am trying to install is 2.4.2 ( though I tried serveral others, non will install.)

The indicated error message at the bottom of the Board manager window is:

Error downloading https.//github.com/esp8266/Arduino/releases/download/2.4.2/esp8266-2.4.2.zip

Also in the output window of the compiler for the Arduino IDE there are multiple javascript messages, to the effect of issues with the certs:

at java.secruity.cert.CertPathBuilder.build(CertPathBuilder.java:280)

The URL that the manager references in the preferences window in order to download the driver is:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Has anyone had this problem ( posting this on 08212018?)

Any suggestions?

Thanks in advance for any assistance!

• Double check the URL: you've posted http.// instead of https:// (note the dot instead of the colon), while the picture displays a correct URL, so it might just be a typo on here only
• Open the problematic URL with your normal browser (or just click the link under the text "The problematic URL" in this sentence).
  If it downloads the ZIP (it should be 15MB and over here it's working fine), you'll know your connection (and the Github-server) are working fine.
• Try to install some other (just a "Normal" Arduino) library that uses HTTPS using the board manager.
  If successful, you'll know Java is installed correctly on your machine

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

I was able to download the zip file...

Was also able to download other board drivers successfully.

When I next turned off my anti-virus program ( long enough for the Boards Manager to download file) it worked!

I am new at using this ESP8266 board and am confident I will have other questions later.

Any good tutorials on use of this board?

Thanks again!
