fix: increase retry attempts when getting events from fullnodes

[luislhl]

Acceptance Criteria

• We should use a higher number of attemps when retrying getting events from the fullnode, because it could be under high load or facing temporary issues

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
• Make sure either the unit tests and/or the QA tests are capable of testing the new features
• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
