python's HGVS module UTA connection error

Question

[wrel2015]

Hi,

I am getting an error whenever I try to connect to the public UTA database hosted by Invitae as part of the HGVS module to try and get the genomic location of the Refseq transcript HGVS term using publicly available data.

Here is what I entered in terminal, if anyone has come across this I would really appreciate your help. Thanks!

>>> import hgvs
>>> import hgvs.parser
>>> hgvsparser = hgvs.parser.Parser()
>>> var_c1 = hgvsparser.parse_hgvs_variant('NM_001197320.1:c.281C>T')
>>> var_c1
SequenceVariant(ac=NM_001197320.1, type=c, posedit=281C>T)
>>> import hgvs.dataproviders.uta
>>> hdp = hgvs.dataproviders.uta.connect()
Traceback (most recent call last):

    Is the server running on host "uta.invitae.com" (54.237.120.108) and accepting

    TCP/IP connections on port 5432?

The site might be down. Try again after a while maybe?

[wrel2015]

I've been trying this for weeks :(

Ohh. Maybe a network problem on your end then? Maybe raise an issue on their bitbucket? They are pretty responsive.

The OP also asked at the hgvs bitbucket page and the issue was solved there. The problem appears to be that the user's institution began blocking outgoing ports.
