@airinfection, from the trace it seems that either the connection configuration is wrong or the database server is down.

[airinfection]

My mysql 5.7 server is running. Username, password and host correct. And i am trying example on your doc.

It was working before interesting..

[airinfection]

stopped working with the last release of crystal.

[bcardiff]

@airinfection travis and local are passing with latest crystal version and mysql 5.7. the specs enforce a login with explicit password.

$ crystal --version
Crystal 0.21.0 (2017-02-21)
$ mysql --version
mysql  Ver 14.14 Distrib 5.7.17, for osx10.12 (x86_64) using  EditLine wrapper
$ crystal spec
169 examples, 0 failures, 0 errors, 0 pending

Is there any new information you could provide?

[airinfection]

is that mysql://username:password@localhost/dbname isnt it

[airinfection]

i installed ubuntu 16.10 it magically worked. still trying to understand why the old one did not work. db collation maybe

[bcardiff]

Closing then, but please, reopen if there is any new info to provide.
