Hi, After upgrading to kibana 7.9, I begun getting an error that I cannot find referenced anywhere. I was wondering if anyone has come across this? ``` TypeError: Failed to fetch at Fetch._callee3$ (https://10.23.45.78:5601/33813/bundles/core/core.entry.js:34:108261) at l (https://10.23.45.78:5601/33813/bundles/kbn-ui-shared-deps/kbn-ui-shared-deps.js:368:155323) at Generator._invoke (https://10.23.45.78:5601/33813/bundles/kbn-ui-shared-deps/kbn-ui-shared-deps.js:368:155076) at Generator.forEach.e.

Seems like a main kibana core error, could you please explain a possible step to reproduce it? Thanks ---

Hi Markov, I simply log in and wait a long time as the kibana red line flashes across the top. I cant seem to do anything else in the meantime. Finally, an error appears in the bottom right corner that says: "An error occurred while trying to set the usage statistics preference." I click for more information and the posted listing is shown. ---

Few questions: - which version were you migrating from? - are you using any third party plugins? - is there any meaningful logs from kibana? if not can you try adding `logging.verbose` option as `true` in the kibana yml file? ---

migrated from 7.8 and no third party components. Turning on verbose gave a flood of data but most of it looked like: > ``` > {"type":"log","@timestamp":"2020-09-01T14:40:49Z","tags":["debug","metrics"],"pid":5566,"message":"Refreshing metrics"} > {"type":"ops","@timestamp":"2020-09-01T14:40:49Z","tags":[],"pid":5566,"os":{"load":[0.0595703125,0.3544921875,0.23193359375],"mem":{"total":67387469824,"free":33859088384},"uptime":16737118},"proc":{"uptime":214.872,"mem":{"rss":545177600,"heapTotal":479436800,"heapUsed":351743144,"external":3280407},"delay":1.5424118041992188},"load":{"requests":{},"responseTimes":{},"sockets":{"http":{"total":0},"https":{"total":0}}},"message":"memory: 335.4MB uptime: 0:03:35 load: [0.06 0.35 0.23] delay: 1.542"} > {"type":"log","@timestamp":"2020-09-01T14:40:52Z","tags":["debug","plugins","taskManager","taskManager"],"pid":5566,"message":"Running task endpoint:user-artifact-packager \"endpoint:user-artifact-packager:1.0.0\""} > {"type":"log","@timestamp":"2020-09-01T14:40:52Z","tags":["debug","plugins","securitySolution","endpoint:user-artifact-packager:1","0","0"],"pid":5566,"message":"User manifest not available yet."} > {"type":"log","@timestamp":"2020-09-01T14:40:54Z","tags":["debug","metrics"],"pid":5566,"message":"Refreshing metrics"} > {"type":"ops","@timestamp":"2020-09-01T14:40:54Z","tags":[],"pid":5566,"os":{"load":[0.0546875,0.3486328125,0.23046875],"mem":{"total":67387469824,"free":33859035136},"uptime":16737123},"proc":{"uptime":219.874,"mem":{"rss":545153024,"heapTotal":479436800,"heapUsed":351927008,"external":3198097},"delay":1.775705337524414},"load":{"requests":{},"responseTimes":{},"sockets":{"http":{"total":0},"https":{"total":0}}},"message":"memory: 335.6MB uptime: 0:03:40 load: [0.05 0.35 0.23] delay: 1.776"} > > ``` It has made the GUI drag. Takes minutes to go from one screen to another. I then set logging to QUIET and found: ``` {"type":"log","@timestamp":"2020-09-02T11:45:32Z","tags":["error","http"],"pid":4137,"message":"{ FetchError: request to https://telemetry.elastic.co/opt_in_status/v2/send failed, reason: connect ETIMEDOUT 99.84.251.54:443\n at ClientRequest.

Im not sure if this is what is causing the original 'fetch' problem though. ---
