Streamlit server consistently failed status check

I keep getting the following error. I’ve tried rebooting, and deleting the app and posting it again. I never get this error when I’m running the app locally. Only when I publish it to streamlit:

Hey @nzylakffa,

Any chance you’re using matplotlib with multiple threads? I found this StackOverflow post which seems to be similar and identifies that as the root cause

Would you mind explaining what that means? I’m not sure what multiple threads are. This is the section where I use matplotlib:

# Draw plot
    fig = plt.figure(figsize=(14,16), dpi= 80)
    plt.scatter(adp_risers_fallers['ADP Change'], adp_risers_fallers.index, s=1500, alpha=.6, color=adp_risers_fallers.colors)
    for x, y, tex in zip(adp_risers_fallers['ADP Change'], adp_risers_fallers.index, adp_risers_fallers['ADP Change']):
        t = plt.text(x, y, round(tex, 1), horizontalalignment='center', 
                     verticalalignment='center', fontdict={'color':'white',
                                                           'size': 15})
    
    # Create start and end dates for title
    start_text = str(start_date)
    end_text = str(end_date)

    # Only keep month and day
    start_text = start_text[5:]
    end_text = end_text[5:]

    # Decorations
    # Lighten borders
    plt.gca().spines["top"].set_alpha(.3)
    plt.gca().spines["bottom"].set_alpha(.3)
    plt.gca().spines["right"].set_alpha(.3)
    plt.gca().spines["left"].set_alpha(.3)

    plt.yticks(adp_risers_fallers.index, adp_risers_fallers['Player'], fontsize=17)
    plt.xticks(fontsize = 17)
    plt.title('10 Biggest Risers & Fallers: ' + start_text + ' -> ' + end_text, fontdict={'size':30})
    plt.xlabel('Change in Underdog ADP', fontdict={'size': 20})
    plt.grid(linestyle='--', alpha=0.5)
    plt.xlim(min(adp_risers_fallers['ADP Change'])-1, max(adp_risers_fallers['ADP Change'])+1)
    plt.axvline(x=0, color='gray', linewidth=0.75)
    st.pyplot(fig)```
