Cannot access learning content

Good morning, everyone.

Before starting this topic, i made sure i did a search, and couldn’t find anything on it.

I’m having a problem with accessing the tutorials “Access Learning Content”. When i tap the link i receive this error:


The website encountered an unexpected error. Please try again later.

Error message “Drupal”

PDOException : SQLSTATE[HY000] [2002] Connection refused in db_table_exists() (line 2820 of /app/web/includes/database/ ).

I’ve been working with these self-paced tutorials then suddenly Sketchup closed. I received a “Bug Splat” report. Sketchup reopened. This happened 2x. I was able to access my account. But when i went to reopen my tutorial on the “Sketchup Fundamentals Practice” (The advanced playground), there was the aforementioned error message. I haven’t been able to access the tutorials since yesterday.

Can anyone help me with this? Thank you in advance. I am still in the trial period of Sketchup Pro.

yippee! looks as if it came back up today! Now i get to play on the “Play Ground” practice again. Working on the handrails. :slight_smile:
