We cannot repeat this on our end. What do you have between the board and the internet?
We are using a Zedboard and the ad9361 card is connected to zedboard. the lan cable is connected to the zedboard
We created the SD card with different images from the link
WE are trying to run a simple LTE exampe using matlab. The first error we get is " unable to connect to IIO server". On debugging trhough the matlab code we found that it is not able to connect to the board.
when we run iio_info -n ip_address_of_zedboard we get the following error "unable to create iio buffer: Broken pipe"
So we tried to run adi_update_tools.sh but we get the above error( See the above post by SAJ)
We cannot even ssh into the board.
The connection hangs on

"Resolving github.com (github.com)... 184.108.40.206, 220.127.116.11" - this looks strange. That address can't be the IP of github.com - it's most likely an IP from your local network. The DNS server should translate the domain name into an IP address, but this doesn't work well on your side. Your issues seem to be caused by your network.
The following is the log from my normal linux desktop machine machine. I can download it easily . My network doesnt have an internal 192. addresses. all the local addresses start with 172... in our network

Same thing doesnt work on zedboard. I suspect the openssl package on linaro version of linux on zedboard but am not able to get through.
I have the latest image 2018 version 2018_R1-2018_06_26.img.xz
I have tried other images too but same result. I changed the zedboard too.
I cannot even ssh into the zedboard.
That's right, 188.8.131.52 seems to be a Public IP that belongs to GitHub, Inc. . Sorry for the confusion.
