Hi Tim are you able to access it from a separate network just fine If you re behind a proxy then I d suggest whitelisting allowing the prefect domain to whoever manages the proxy I don t quite think this is a prefect issue though

Tim-Oliver · Answer

From a separate network it works I can ask them but they are very strict with their rules here Interestingly I never had such an issue with Prefect 1

Tim-Oliver · Answer

Could you suggest some address that I could test ping the connection

Christopher Boyd · Answer

The API `<http api prefect io|api prefect io>`

Christopher Boyd · Answer

it should be your prefect api url minus the tenant workspace

Christopher Boyd · Answer

and prefect 1 was a separate URL

Christopher Boyd · Answer

you should be able to curl vvv with no parameter you should get a response ``` Connection 0 to host left intact GET query missing ``` If you are behind a proxy it should show in the session connection and a cache miss response from the proxy

Christopher Boyd · Answer

you can also check your proxy settings `echo $HTTP PROXY amp amp echo $HTTPS PROXY`

Christopher Boyd · Answer

you can probably set a no proxy locally as well export `no proxy= `

Tim-Oliver · Answer

``` prefect2 curl vvv Uses proxy env variable https proxy == Trying 172 27 28 7 8080 Connected to 172 27 28 7 port 8080 0 allocate connect buffer Establish HTTP proxy tunnel to gt CONNECT HTTP 1 1 gt Host gt User Agent curl 7 81 0 gt Proxy Connection Keep Alive gt lt HTTP 1 1 200 Connection established lt Proxy replied 200 to CONNECT request CONNECT phase completed ALPN offering h2 ALPN offering http 1 1```

Tim-Oliver · Answer

If I set `no proxy` I get ``` prefect2 curl vvv Uses proxy env variable no proxy == Trying 34 111 157 195 443 Trying 2600 1901 0 cb3c 443 Immediate connect fail for 2600 1901 0 cb3c Network is unreachable``` Which makes sense

Zanie · Answer

There s an issue to add a setting for this to only use the proxy for traffic from the Prefect client
