PatZilla croaks with “HTTPBadGateway: Could not connect to OPS servers” #9

Closed amotl closed 5 years ago

amotl commented 5 years ago

After installing PatZilla in development mode on a fresh Ubuntu 18.10 box, customers are reporting a problem to us. While PatZilla starts fine and is apparently properly configured, it bails out when actually accessing the OPS services with this exception:

  File "/home/develop/patselect-dev/ip-navigator/patzilla/access/epo/ops/client.py", line 192, in request
    raise error
HTTPBadGateway: Could not connect to OPS servers.

We have been able to partly fix this in the epo-ops-client branch, so you might want to use the epo-ops-client branch if you're in a hurry. We are already working on the next release which will remedy this problem as well as some other issues introduced recently. Please bear with us.

Also wanted to let you know we are already tracking this over at meta: PatZilla croaks with “HTTPBadGateway: Could not connect to OPS servers”

Solution

PatZilla version 0.162.0 resolves the problem with OPS connectivity, as confirmed by @ElvezPelvez and others. Thanks and enjoy your research.

Background

As @aghster asked over there at #8:

The issue explained [here] seems to be related to a python update (@amotl, did I get this right?)

Actually, we don't know for sure. But as the switchover from a custom OPS client implementation to George Song's great python-epo-ops-client library was long overdue, we just took the chance to finally implement it. Thanks, @gsong!

Great and thanks a lot!

Btw. where can I leave feature requests? I'd really love to have a function to bulk download selected documents (if possible even specific regarding their kind code)...

Dear @ElvezPelvez,

appreciate it, we will be happy to hear about feature requests. Because we found Discourse very suitable for managing such things, we would like to invite you over at meta https://meta.ip-tools.org/ and encourage you to drop your suggestions into the PatZilla development category.

With kind regards, Andreas.
