Hi Brian,

I think this might be caused by this issue:

https://github.com/perfsonar/psconfig-web/issues/219

This should be fixed in 4.4.2, but in the meantime, try this:

$ sudo cp /usr/lib/perfsonar/psconfig-web-admin/auth/node_modules/moment/moment.js /usr/lib/perfsonar/psconfig-web-admin/shared/node_modules/moment/

And restarting perfsonar-psconfig-web-admin-publisher.service.

Subject: [perfsonar-user] PWA config not making it to MaDDash

Hello,

I’ve been troubleshooting some problems with latency and throughput meshes in MaDDash. I had generated them with PWA and after troubleshooting PWA doesn’t seem to be generating a config anymore. I had re-installed PWA and MaDDash during my troubleshooting and both websites still load up. MaDDash shows no meshes, and on PWA I’m able to add hosts, hosts groups, testspecs and setup a config. However when I hit the “pSConfig” button on the configs page it throws a 502 proxy error:

Proxy Error

The proxy server received an invalid response from an upstream server.

The proxy server could not handle the request GET /pwa/pub/config/networknebraska.

Reason: Error reading from remote server

When I go to http://<hostname>/pwa/pub/config I get the following:

[{"include":["http://<hostname>/pwa/pub/config/networknebraska"]}]

When I go to http://<hostname>/pwa/api/pwa/health I get the following:

{"status":"failed","msg":"pwacache is reporting unusually low hosts count..","cache":{"hosts":0,"update_time":1634162480319}}

This machine is running perfSONAR 4.4.1-1.el7, running on CentOS 7.9.2009. I’m not sure where else to go from here, could someone point me in the right direction please?

Thanks.
