Telegraf build asks for username

All of a sudden I am getting below prompt while building telegraf 1.12.2:
~/telegraf]# make
dep ensure -vendor-only
Username for ‘’:

Even if I enter a username, it still gets stuck and doesn’t move further.

In the Jenkins job I get this error:

dep ensure -vendor-only grouped write of manifest, lock and vendor:
error while writing out vendor tree: failed to write dep tree:
failed to export (1) failed to list versions for
fatal: could not read Username for ‘’: No such device or address : exit status 128 make[1]: *** [deps] Error 1

Used to build it regularly in the past and it never used to ask for username, not sure what changed in last 10 days.
Please help me fix the issue.
