Riot or Matrix Timing out when connecting to large homeservers such as matrix.org

[iokiwi]

Try to join MatrixHQ:matrix.org

Sits for ages trying to connect any may or may not eventually fail.

Shows cannot reach home server even in local channels

Potentially a problem with request / response size?

Works ok on riot.im webclient

[iokiwi]

Or may be an issue with maximum response size
