ansible tower cannot get license list after installation - ansible

Question

I am trying out ansible tower on Red Hat Enterprise Linux Server 7.7 (Maipo) but could not get my license list. Following error occurs
It seems that the server cannot connect to "subscription.rhsm.redhat.com"

During handling of the above exception, another exception occurred:

i can curl "subscription.rhsm.redhat.com" so firewall is not blocking it.
and also configured proxy parameters in /etc/rhsm/rhsm.conf
sslCACert is pointing to /usr/share/rhn/RHNS-CA-CERT
DNS server is present in /etc/resolv.conf
what am i missing? please help me out.

I had the same problem today, it seems we need a direct internet access. But I have find a way to bypass this and hardcode the proxy:
[root#ansible requests]# pwd
/var/lib/awx/venv/awx/lib64/python3.6/site-packages/requests
[root#ansible requests]# grep 192.168.5.25 *
grep: __pycache__: est un dossier
sessions.py: 'http': 'http://192.168.5.25:3128',
sessions.py: 'https': 'http://192.168.5.25:3128',
[root#ansible requests]# vi sessions.py
def __init__(self):
366
367 #: A case-insensitive dictionary of headers to be sent on each
368 #: :class:`Request <Request>` sent from this
369 #: :class:`Session <Session>`.
370 self.headers = default_headers()
371
372 #: Default Authentication tuple or object to attach to
373 #: :class:`Request <Request>`.
374 self.auth = None
375
376 #: Dictionary mapping protocol or protocol and host to the URL of the proxy
377 #: (e.g. {'http': 'foo.bar:3128', 'http://host.name': 'foo.bar:4012'}) to
378 #: be used on each :class:`Request <Request>`.
379 self.proxies = {
380 'http': 'http://192.168.5.25:3128',
381 'https': 'http://192.168.5.25:3128',
382 }
ADD these 4 lines with your proxy config.
It worked for me and I got my license. Please, don't forget to backup the file sessions.py.
