Error Log while creating SSL

Hi,

I was able to generate SSL with no problem until recently. Now it takes so long and not finalizing. When I checked the logs I see below messages:

[09-24-09-Sun-Sep-2019] Request body exceeded settings.DATA_UPLOAD_MAX_MEMORY_SIZE.
[09-28-18-Sun-Sep-2019] Trying to obtain SSL for: [REDACTED] and: [REDACTED]

[09-28-18-Sun-Sep-2019] Trying to obtain SSL for: [REDACTED] and: [REDACTED]

Any Idea how to fix this issue?
